Had Len a street cat 12 months now , approx 6 yrs from a rescue centre, they were open from the start saying he’d never be a lap cat, and had a biting and swiping issue. 12 months later, hes a lap cat when he chooses, follows me everywhere, never goes out unless he follows me round the garden. The bites are mainly nibbles now, although there’s still some random ouch ones..never hard enough to draw blood though. One problem..his claws.., he strokes my face in the morning he’s trying to be gentle but his damn claws are out. He sometimes wants to play rough and catches me by surprise and he cuts me up. There no aggression there now at all. Can you teach a cat to retract his claws?. Trimmings a no go been trying since I got him to touch his paws, he will bite then and mean it, So unless I put him in a straight jacket can’t see that being a option.
