I have a feral cat that has adopted me. She had already been spayed and had her ear tipped but she was starving and somehow found her way to my house. I fed her and of course she stayed. I bought a small insulated dog house and put this heated pad in and put it in a sheltered spot in my yard. She loves it and I feel comfortable leaving her outside. Feral cats are wild but she needed shelter and this is fantastic. She keeps my yard free from rats and mice to return the favor!
