Hi, we got a beautiful 6 year old rescue cat in November. Hes very loving and we have got really close - he sleeps on my bed some times and will normally sit on me of an evening on the sofa. Hes nervous and I have worked hard to gain his trust. All fine.
We were away for 3 nights (first time we have left him), and on our return, he is acting really strangely. He gets on me when I am on the sofa like normal, but instead of falling asleep, he paces all over my tummy and legs (I am stretched out on the sofa) biting my clothing and getting a bit frantic. He has his claws out so it hurts and he gets bits of my jeans and holds it in his teeth for about 20 seconds, and then he (painfully!) climbs to another part of me and bites there.
Hes had the chop, but it seems like its something to do with him being on heat - is this a thing? I am clueless, does anyone have any ideas of whats wrong with him?
