Am planning for my first pet cat. What should I be asking the sellers of the cats other than are they healthy/vaccinated/wormed? All the ones I've messaged are offering visits to see kittens with mum (good, I think). What else to look out for? And what cat paraphernalia should I get, other than a carrying thing and some toys? Do cats sleep in beds? (I've never known one sleep in a specific cat bed but maybe some do?). All tips welcome.
