TNR (trap-neuter-release) programs are exactly what they sound like: you trap a feral/stray cat, take it to a veterinarian for neutering and tagging, then release it. It's a proven effective way to gradually reduce the population without triggering the vacuum effect. The cats need to recover from the surgery for about a day, and since not all veterinarians are willing to house the cat at their clinics, recovery should be done at home. What setup should I have? Obviously I'll keep the cat away from any animals or humans, but what else should the area have? How much space should the cat have during recovery? This recovery area will be outside and I live in Los Angeles.
