I never like going to the SPCA unless I'm adopting a kitty. My last five visit unfortunately was for that. I live in a mobilehome park and my neighbor want to continue to breed feral kittens and turn them into strays. I've been trying to get someone to help me with this madness but no one will. I don't understand how the SPCA doesn't or can't get authority to stop this man from producing cats that are just going to be killed because they are raised in the wild and aggressive. If I was in the city then they would intervene but because I'm in a mobilehome park they won't. I'm sure the five i took in didn't have a chance. And it's not the SPCA fault either. How they going to adopt a cat or kittens out if it hisses at you or can't be catch? They cant no one can not even a no kill shelter they won't even except it if it can't be rehabilitate. As long as my neighbor continues to breed then they will die . So if you know anyone that will help me stop the killing let me know.
