My cat has been acting strangely since this morning. He keeps walking around in slow motion, sniffing everything. He has been getting freaked out by things left lying around the house that have always been there. He is acting like he is seeing hallucinations. He is an 1 year old indoor Scottish Fold and nothing different has happened since last night, when he was completely normal! He can not sleep very well. Every time he closes his eyes he acts like he hears something and opens his eyes immediately. I watched the videos about "hyperesthesia". He does not look like he has it. We tested his vision and he sees quite well. Any other ideas? I have seen a few people wrote about this exact same behaviour at the forums but none of them got the answer. Please help!
