My cat has been acting strangely since I've seen him this morning.
He keeps walking around in slow motion, sniffing everything and being on edge. He has been getting freaked out by things left lying around the house that have always been there. For example, ds' plastic sword and does that paw tapping thing with it. He is acting like he is completely paranoid.
He is an indoor cat and nothing different has happened since last night, when he was completely normal! It's almost as if he can sense another cat in the house - which is not the case.
Any ideas? He was so edge he didn't have his usual morning naps, but is now fast asleep.
