My 3 year old (neutered - at approx 4 months I think) male cat is becoming increasingly vicious/nasty.
He was born in a house with children so was used to being handled from birth/early on.
He loves to be near us, ie sit next to us, he will literally come & sit & watch DC build lego/sit next to us while we play a boardgame, but isnt keen on being stroked or handled, which is fine, we don’t!
Occasionally he will come to us for affection/get on our knee/rub against us, but this will always end with a bite after a minute or so.
But his unprovoked biting/attacks are getting worse & worse.
99% of the time its me he goes for, so I can hand on heart say I know its unprovoked, DC is petrified of him tbh & doesn’t go near him.
If he wants feeding, he will come & attack our feet - I do mean attack as well, not a nip.
He has bitten my hand badly twice in the last fortnight, both times I was sitting next to him on the floor, hadn't moved at all - both times I was leaning my weight on the hand he bit, so I wasnt moving it around or moving it towards him.
He has been checked by vet all ok, tried plug ins, no change. This isnt new behaviour, its worsening of existing behaviour, he has always been bitey.
If he was a dog, he would have been PTS by now. I live in hope of having another baby & theres no way I could trust him around one.
He has plenty of food/water & cat flap so can come & go as he pleases.
What can I do to stop this behaviour? Vet had no suggestions really.
If I try to pick him up to remove him after the bite, he will really attack even more. Definitely doesn't seem scared at the time, as he doesn't run away or even move, continues sitting/laying where he is!!
