We adopted a 4 year old tom cat a year ago. He'd only just been castrated at the time.
He's just so vicious. He's very big and has quite a lot of battle scars which should have been a bit of a red flag but for some reason he was the one we all wanted so we took him home.
He seems to quite like living with us and the kids love him but he just hasn't warmed to us at all. We can't pick him up or stroke him really as he's just too violent. He attacks my other older tom cat so I've had to separate them. Also attacked the vet twice.
He terrorises the neighbourhood cats too. My neighbour told me he's been regularly attacking her two cats and actually drawing blood.
I've thought about a felliway defused but won't that only calm him whilst he's in the home? Also he's caused probably about a thousand pounds worth of damage in the home - shredded carpet, sofa and chairs. He won't use the scratching post at all.
I'd hoped he'd calm down over time but it's been a year now and he's still exactly the same. He walks round with his hackles up - seems to have the fur on his spine permanently stood up. He will come and rub himself against us but if I stroke him he'll scratch.
