ok..so i went to check out the kittys today at Petsmart from the shelter...Now ,remember, my Cosmo is 2 1/2 and I have never heard him hiss or growl...he is awesome. First there was an orange and white one who looked like my kittys twin , he was acting really, hyper and playful, trying to climb the cage, swatting at everything, etc...(maybe too hyper for my cat?).The second one was a medium haired orange kitty who was stunning but for some reason, not neutered yet (they will pay for it) and had a tiny syringe of yellow medicine hanging from his crate ( she wasnt sure whY) and the third who she fostered ( who I thought would be the best since she said she gives her fosters free roam and has big dogs and other cats and they all got along) who hissed and growled when I was holding her. OF course, the volunteer said she was shocked because she never heard her do this before. So...judging from the above info...what would you do? Oh by the way, the first two , the volunteer said, were fostered with dogs but were kept crated. Any advice would be infinitely appreciated.....Thanks...
