Well Buttercup has been with us for a couple of days And Ive noticed that she does not startle at any loud noises. So I decided to test my theory on her possibly being deaf. I put her on the floor and let her play and then snuck up behind her and went SSSSSSSSSSSSSSS kinda like a cat hissing, nothing, no reaction what so ever. Then I tried it again by clapping, once again nothing. So my husband distracted her and I snapped my fingers next to her ears, once again no reaction, not even her ear moving to the sound. Is this a pretty good indication that she can't hear? If it is, what are some tips on training her? when Cali was young and did something bad I would clap loudly and say "no,no!". If a cat can't hear how do you teach them that what they are doing is wrong? Any advice from people who have deaf cats would be awesome.
