Can I spay my neighbors cat? First off, I love kittens. Second, I do TNR for for the strays in my area to help keep the population down and keep the city from doing feral sweeps/kills. However- one of my neighbors has an unspayed female who just had another litter and is bringing the litter to my yard. Which means- I buy more KMR. I buy terramycin ointment to fix the goopy eyes. I take them to the vet. And buy antibiotics as needed . I adopt as many as I can out. And I have to deal with it if a sick one or runt failing to thrive has to be put to sleep. The owner of the cat will not take any responsibility for it except for feeding (which I end up doing also). Now if I trap the unspayed cat and have her spayed is there any legal problems with that? Yes, I am using the internat as my lawyer. Advice?
