What is a feral cat?
Feral cats cannot be picked up or handled by humans. They are the offspring of outdoor cats who roam free and are not sterilized. These wild cats are often many generations removed from human ownership and cannot be placed into a typical home situation.
What is Trap-Neuter-Return?
Trap-Neuter-Return (TNR) is a method of humanely controlling community/feral cat populations. TNR involves several steps. First, the cats are humanely trapped. The cats are then sterilized and vaccinated and receive an ear-tip (a small notch in the cat’s left ear that confirms that he or she has been sterilized). Socialized cats are adopted into homes, and cats who are truly feral are returned to their original location.
What are the other options for dealing with community cat populations?
Community cat populations can be dealt with in one of four ways: trap and kill, whereby cats are caught and euthanized; trap and remove, whereby cats are trapped and relocated; trap and return (TNR); and doing nothing or withholding food from the cats.
What are the advantages of Trap-Neuter-Return?
There are many advantages of Trap-Neuter-Return. Besides ending the breeding of more unwanted cats, it also reduces the number of free-roaming cats. Additionally, TNR stops many nuisance cat behaviors like spraying, yowling and fighting. Through TNR, cats are vaccinated and sterilized, and unhealthy cats are removed.
What traps are best?
To utilize our TNR services, it is important that you use the appropriate equipment to trap a feral cat.
The most commonly used traps are Tomahawk and Tru Catch constructed of 16 gauge 1" x 1" galvanized wire mesh. We recommend models that have both front and back doors and are 30" or 36" long by 12" high since the cats will be spending both pre-surgery holding and post-surgery recovery time in the trap. Two-door traps of the right height make caring for the cats safer and easier for you as a caretaker and increase the safety of veterinary staff handling more fractious animals.
