Hi all,
A neighbourhood cat has been visiting me for over a year, he seems very keen to move in and if I'm honest I've become equally attached 
I've never fed him as that would be unfair to his owners but he spends about 90% of his time in my garden/ greenhouse/ house. He only goes home for food!
(I live alone and have no other pets; he comes from a household of teens, dogs and other cats)
I plucked up the courage today to explain to his owners the reason they never see him is that he's always on my property. They were really lovely and were just glad he's happy and loved. Then they asked me if I'd like to take him on 
I'd do it in a heartbeat but I need to consider the practicalities.
The last time I had a cat I fostered so all costs were taken care of. My childhood cats were obviously looked after by my parents! What sort of associated costs am I looking at? I can afford food and already own a hooded litter tray and carrier, plus bowls, toys etc. I don't have a catflap (neither do his current owners) but he loves being out in the garden and I have a cushion for him in the greenhouse which he adores.
I'm most worried about vet costs/ insurance (a relative is trying to discourage me) as I'm on a low wage. The cat's not insured and I'm sceptical that I'd get an accurate account of his vet history as they're keen for me to take him on
I've been told he's neutered and they've had him since he was a kitten (he's 7yrs old).
Could you kind cat people tell me if I've forgotten something? I'm researching at the moment
