My friend is feeding 4 feral cats. She managed take 3 of them to Animal Control for spray & neuter and they returned them back. The forth cat is very agressive (female) and she is getting kittens every half of year. The first problem is give away the kittens. But the main problem to catch this cat and get it sprayed. She tried the cage, she tried the different treats to lure her in. Nothing works (cat is too smart). Now she get advice to get the fish net to catch her in, but not sure if she could make it. Is there on the market something like sleeping pills for the cats, so she can feed it to her and get her to Animal Control for spray? She is agressive now, especially with the kittens and she doesn't let the other three cats (that are neutered) to come close to food and to house. Does someone has an advice?
