It's 3 and a half weeks he's been here - I have taken it very slowly though. She's older and had a failed fostering with another cat 3yrs ago when she was found as a stray. She's pretty territorial for such a small cat! Next door's bruiser has been put in his place, in his garden sometimes!
Babycat has his second jabs and microchip next week, but neutering not for another 3 months - you were right, cozie that they don't want to do it until he's properly into puberty/6m+. But otherwise I really like and trust my vets - and don't have the energy to 'shop around'. So we wait - for now anyway.
