windpipe and cut off her breathing. Because making sure she is lying in a good positionmay require handling the cat, it’s always best if cats in the unconscious stage are notreturned to the caretaker unless veterinary staff is present. Ideally, only an experiencedveterinarian or veterinary technician would decide whether it is safe to touch a sedatedferal cat. However, if veterinary staff is not present and you’re concerned, first makeextra sure the cat is actually unconscious and then gently straighten her out so she’s lyingon her side with her neck unbent.In the second stage of withdrawal, depending on the type of anesthetic used, the catmay shake or twitch a fair amount, as though violently shivering or in a mild seizure.This is nothing to be alarmed about. Anesthesia causes the cat to lose control over theregulation of her body temperature, which drops. As the drugs wear off, the cat shiversto regain warmth. Because of this drop in body temperature, it’s vital that a cat comingout of surgery be placed in a warm space for recovery (at least 65 degrees Fahrenheit).During the shivering stage and thereafter, the cat should be kept confined in her trap withall doors shut and locked.In the third stage, the cat has regained consciousness, but not full control over bodilymovements. The cat may struggle to move about and fall over or swoon, appearing in adrunken state. She may bang up against the sides of the trap, trying to get out. The trapshould be covered with a sheet at this point to provide a sense of security.Finally, upon full withdrawal from anesthesia, the cat will lie or sit quietly, appearingperhaps a little tired but otherwise alert.If the cats are returned to you before they’ve reached the final stage, be sure to ask theveterinarian how long it should take before they get there. Generally speaking, if it takesmore than a couple of hours for a cat to go from unconscious to sitting or lying on hisbelly, that is cause for concern and veterinary staff should be consulted.• FoodAdult cats can be fed three or four hours after full anesthetic withdrawal. If the catsare being transported from the clinic, wait until they’ve arrived at the holding spacebefore feeding. Start out providing about half the size of a normal meal in case theirstomachs are upset from the anesthesia. The next morning, full portions can be given.Water should be provided as soon as the cats are fully awake. Sometimes the cats’mouths become dry from the anesthesia and at first they’ll drink more than usual. Kittensmay need to eat sooner than three or four hours after becoming fully alert, depending ontheir age. Ask your veterinarian how long you should wait before feeding them. FIV/FeLV testingThe vast majority of TNR programs do not perform FIV/FeLV testing on every feralcat, but only for those showing serious illness or for those being offered for adoption.There are several good reasons for this policy:120
1. With limited resources available, spay/neuter takes priorityOne study found the prevalence of FIV (feline immunodeficiency virus) and FeLV(feline leukemia virus) in the unowned, free-roaming cat population – approximately 8%tested positive for one or the other virus 2 - is similar to that in the pet cat population. Onaverage then, based on this study, testing 1000 feral cats will result in the identification of80 cats testing positive for either FIV or FeLV. Even assuming a low cost of $12 per test,that would mean spending $12,000 to identify 80 cats with positive test results. Thatsame $12,000, at an average spay/neuter cost of $50, could be put instead towardsneutering 240 ferals. Because funds are limited and the primary goal of TNR is notdisease control but to stem overpopulation, neutering 240 more cats should take priorityover identifying 80 positive test results.In addition, as explained in detail below, correct veterinary protocol requires retestingat a later date to confirm the initial diagnosis. Retesting isn’t practical with feral cats andis rarely done. Instead, a feral cat’s fate is determined on the basis of only one test, aquestionable practice, especially if the cat is showing no signs of illness.2. Spay/neuter can be a more effective means of disease preventionEven if disease prevention is considered an important objective for a TNR program,investing in spay/neuter may have more benefits than trying to identify and cull positivecats. With respect to FIV, the primary mode of transmission is deep bite wounds. Thistype of injury is most often inflicted by male cats during fights provoked by matingbehavior. Neutering males thus eliminates the most prevalent form of FIV transmission.With respect to FeLV, experience and research has shown that kittens are the greatest “atrisk” population among feral cats, 3 probably because their immature immune systems arenot capable of fighting off infection. Spay/neuter, of course, prevents the birth of kittensand hence the spread of the virus. Spay/neuter eliminates sexual activity, another route ofFeLV transmission.3. The kinds of tests normally used on ferals are unreliableThe FIV/FeLV “test” is a misnomer. Each virus is actually tested for separately,although the tests may be combined into one kit. There are also different kinds of testsavailable for each virus. Depending on which virus is being tested for and which type oftest is being used, the results may be unreliable.• Feline Immunodeficiency Virus (FIV)When it comes to testing feral cats for the FIV virus, most veterinarians and clinicsuse the ELISA (Enzyme-Linked Immunosorbent Assay) test.
