Talk to me about kittens, hoping to have one very soon, and my old cat who sadly passed last month was with me from the age of 6 to 17 but I never knew him as a kitten! So, what do I need to do / know?? Litter tray, litter, bed, blanket, toys, what else?? Vet registering, flea and worming treatments, when do you castrate them?? Excited but nervous!
