General Terminology

Terms Related Specifically to Feral Cats

Medical Terminology

Spay - the medical term is ovariohysterectomy.  In this major abdominal surgery the pet's ovaries and uterus are removed.  There is no evidence that a pet suffers from any personality or emotional harm by having their ovaries removed.  The uterus is also removed to insure that it does not become a source of infection over a period of time.   If the surgeon simply tied or obstructed the Fallopian tubes (the channel where the eggs must pass into the uterus) in order to make the female dog or cat sterile, she would still come into heat, attract males, and attempt to breed.  Experience has shown that the best procedure is to perform a complete ovariohysterectomy.

Neuter - another term is castration.  In this surgery the doctor makes an incision in front of the scrotum and through that incision accesses each testicle.  The fibrous coverings of the testicles are incised and each testicle is removed after securely ligating the blood vessels that attach to each testicle.  The benefits of having a dog and cat neutered are well documented. And to simply do a vasectomy to render the male sterile would not alleviate the scent marking, desire to breed, territorial defense and other testosterone driven behaviors. Even in guard dogs and hunting dogs, many owners report improved behavior and manageability when the dog has been neutered.

Targeted Sterilization - The sterilization of animals known to be sterilized at rates lower than the general population of household companion animals, such as cats and dogs in households poor enough to receive public assistance, cats and dogs admitted to public or private animal shelters and free-roaming cats. Targeting maximizes the impact of a clinic or program's limited funds.

Effective Sterilization - The sterilization of a cat or dog which would not have occurred without the help of a program's reduced rate or subsidy. For instance, a low-cost clinic which does 15,000 sterilizations each year may have really accomplished only 5,000 effective sterilizations if 10,000 of the animals would have been sterilized anyway, without its reduced rate or subsidy.

Spay Blitz - is a pet-care event, the centerpiece of which is a free (or very low-cost) spay/neuter demonstration clinic. Elements are:
  • Total community involvement, including government and civic leaders as well as school children
  • A goal of 70% sterilization, including pups and kittens, nursing mothers and cats/dogs in heat
  • Surgery and vaccinations are free - or as close to it as possible - for those in financial need or with multiple animals

Early Spay/Neuter - Ovariohysterectories/gonadectomies (spay/neuter surgery) for puppies and kittens eight to sixteen weeks of age. The American Veterinary Medical Association approved early spay/neuter in 1996, in an effort to stem the overpopulation problem of companion animals.

Heat - Estrus ("heat") is the mating period of female animals. When estrus occurs, animals are said to be "in heat" or "in season."

  • Cats: Cats normally have their first estrous cycle between 4 and 6 months of age, with the average age around 5 months.  The female cat has 2-4 estrous periods every year, each lasting 15-22 days. If she is bred, estrus seldom lasts more than 4 days.

    If successful mating does not occur, estrus may last for 7-10 days and recur at 15- to 21-day intervals. It is possible for an unmated female to cycle every 3-4 weeks indefinitely. 

    Cats also have an estrous period 1-6 weeks after giving birth, so a female may be nursing one litter while pregnant with another.

    Behavior
    Since there is usually no obvious vaginal discharge or swelling of the genitals during estrus in cats, as is seen in dogs, behavioral changes are the only obvious signs that your cat is in estrus.

    A cat in estrus often carries her tail to one side, keeps her hindquarters elevated and seems unusually affectionate. She will rolling on the floor and seems much more restless than usual. The cat's voice seems more piercing than usual and she may "call" for 1-2 days before she accepts the male. 

  • Dogs: Estrus or Heat cycle - The average heat cycle for a dog is approximately 3 weeks (21 days) and since this is an average, some heats are shorter (as little as 7-10 days), others are longer (4 weeks or more).

    Average times between heat periods is seven months but some dogs can cycle as early as every 4 months, some once a year. Lengths of heat cycles and intervals between cycles are different for each dog but most dogs hit somewhere close to the averages.

    Physical Symptoms:
    Include bleeding from the vulva, swelling of the vulva, possible increase in urination and the most noticeable, male dogs hanging around the house.

    The next cycle usually begins about 7 months from the start of the last heat cycle, not the end of that cycle but again this varies from dog to dog. The interval stays the same even if she becomes pregnant.

Feral Cat - Feral means "gone wild." Feral cats can be the offspring of stray or abandoned domestic cats who have reverted to a wild state. They can also be the offspring of feral cats who have lived in a wild state for some generations. Finally, they can be domestic cats that have run off, or have been abandoned, or have "gone feral" meaning "gone wild." Feral Cats live in family groups called colonies and can be found anywhere there is food. Feral cats can survive almost anywhere, and are found all over the world.

TNR - Trap-Neuter-Return is a humane, non-lethal approach to feral cat population control. Alley Cat Allies (ACA) promotes a comprehensive management plan where healthy feral cats are sterilized and vaccinated, then returned to their habitat and provided with long-term care, including food and shelter.

Managed Colony - A feral cat colony becomes a managed colony when a comprehensive population control plan is implemented that includes sterilization and ear tipping, as well as provision of food and shelter. Feral cats are dependant on a caretaker(s) to enact this plan and provide long-term support. Besides the obvious advantage of population control, the cats are better able to care for themselves since they no longer have to put all of their energy into producing and caring for offspring. A properly managed colony is a healthy and stable colony. No kittens are born because all of the feral cats are sterilized, and the colony is monitored on a daily basis.

Eartipping - A technique of painlessly removing a quarter-inch off the top of a feral cat’s left ear while the cat is anesthetized for spaying/neutering. Eartipping is the universal symbol of and only proven way to permanently identify (both close up and from a distance) a feral cat that has been evaluated, vaccinated, and sterilized. Eartipping ensures that a sterile cat will not undergo unnecessary repeat trapping and surgery.

Vacuum Effect - Feral cats establish territories based on availability of food sources and shelter. When cats are removed from this environment, more cats quickly move in to take advantage of those resources. These new unsterilized cats will breed prolifically. The vacuum effect has been documented around the world.

Crypt/Undescended Testical - An improperly developed testis may never leave the abdomen, and it may not produce the hormones that induce secondary sex characters. A testis lodged in the canal may well produce these secondary sex characters, but cannot produce spermatozoa. Failure of both testicles to descend is uncommon. Usually only one testis is involved and the other produces sufficient spermatozoa to render the animal fertile. - Sauders Comprehensive Veterinary Dictionary (2d ed), 1999 [DC Blood & VP Studdert]

Rabies - A virus spread through bites or saliva of infected animals that attacks nerve tissue in warm-blooded animals, including humans. The disease develops over 10 days to several months. Infected animals may be withdrawn or become unnaturally aggressive and attack. Death always occurs once a rabies-infected animal shows signs of the disease. Both cats and dogs should be vaccinated for rabies as it is required in many states and poses a serious health threat. Cats may be vaccinated as early as 12 weeks of age; dogs 4 - 6 weeks. Please note that the occurrence of rabies is well below 1 percent according to Pfizer, Inc. - manufacturer of various vaccinations. - The Pet Center*

Distemper - An airborne disease caused by the panleukopenia virus that can cause death. Symptoms include: fever, loss of appetite, vomiting, diarrhea, dehydration, weakness, tremors and incoordination. There is a vaccine against this virus and because it is difficult to prevent exposure, all cats and dogs should be vaccinated. - The Pet Center*

Feline Respiratory Disease- A respiratory infection. This disease can be easily passed from one cat to another by direct contact or droplets in the air from coughing or sneezing. Symptoms include: watery or sticky discharge from the nose and eyes, nose and mouth sores, fever, lethargy and loss of appetite. The disease can be caused by one of two viruses - feline rhinotracheitis virus or feline calicivirus. The rhinotracheitis virus tends to be more severe and can cause death, especially in kittens or abortion in pregnant cats. There are vaccines against these viruses. - - The Pet Center*

Feline Leukemia - Abbreviated FeLV is a virus that suppresses the cats’ immune system, leaving it unable to fight off other infections such as pneumonia. Any cat that is in continuous poor health or that often becomes sick with infections or fever may have feline leukemia. Veterinarians can do a simply blood test to find out if your cat is infected with FeLV. A feline leukemia vaccination is available and is an important part of preventive health programs. - - The Pet Center*
FIV Feline Immunodeficiency Virus - A retrovirus specific to cats, FIV is transmitted from cat to cat primarily by deep bites, as the virus is shed in the saliva. Perhaps the most prevalent method of transmission is bite wounds in fighting cats, especially roaming males. Intimate contact through grooming, sharing food, etc. does not spread the virus. Overall, FIV is less common than FeLV. FIV+ cats often live long, symptom-free lives. - Alley Cat Allies

This disease in cats is similar to the Human Immune Deficiency Virus (HIV) seen in humans. But the FIV virus is found only in felines. The evidence seems to indicate that this disease is spread mainly through the bite of an infected cat. Like FeLV this disease suppresses the immune system’s strength so affected cats are likely to develop all sorts of infections in the urinary tract, respiratory tract, intestine and kidneys. No vaccine is available for this disease at this time.- The Pet Center*

FIP - Feline Infectious Pertonitis is caused by a virus. Cats that show signs of infection almost always die from it. Symptoms include: enlarged abdomen, fever, weight loss and possibly eye lesions. A vaccine is available for this virus. - The Pet Center*

Pyometra - The term means pus in the uterus. Any time a veterinarian is presented with a dog or cat suffering from pyometra the condition is considered serious and immediate surgery is nearly always indicated. For whatever reason, if your female dog or cat hasn't been spayed be alert for pyometra.- The Pet Center*
