Our street has been feeding a stray for about 3 years..maybe more, now. When he first appeared he was a skinny, unwell entire male.
Gradually he got less skinny, and I managed to flea treat him, but he stayed outside at all times..til he got really unwell and I caught him, took him to the vets..no chip...had him patched up and neutered.
He still wouldn't come in so we made him a hutch and he started sleeping in that. Eventually he started coming into the hall, then the kitchen.
Then 3 weeks ago, I opened the door, he marched in, snuggled up on the sofa and stayed!
Since then he's been on the sofa..or my lap!!!! He bites, he is terrified of house noises and he likes to swipe the dog (who has taken it in her stride!) but he is also very affectionate.
Last night I went to bed, the dog came with me as usual..she sleeps on the floor. At 1am I stirred, rolled over and discovered said cat.. IN my bed..between dh and me !!!!!!!!!! When I moved a little he purred.
I think he's our cat now?!
I took him for a check up tonight (he didn't like that!) as I thought his teeth looked iffy, and yes he needs a dental. Vet thinks he's about 8 years old, and bless her refused to charge me for the consult. He's also slightly overweight now...not surprising as he has a 'desperate for any food' mentality.
His name is now officially Sebastian :) and he likes my heated throw 
Isn't he beautiful? From skeletal scabby and flea ridden to plump beastie!
