I foster rescue kittens and have people coming to meet the kittens.
Food, toys and beds are always something to discuss.
Find out what food the kitten is used to eating. I'm currently struggling with one of a litter who will only eat one brand of food, she will almost eating nothing else, so because she's from a troubled background, I just want her to eat enough to grow and develop. To me this does not seem to be the appropriate time to force 'worthy' food on a kitten who will only eat Felix .
Many will eat anything, others will only eat certain brands, which may or may not be the same as what you would like them to eat. I would like all my own cats and the fosters to eat canned high meat food because this is best for them and the environment (no unrecyclable sachets, the terra whatsit scheme is not practical for me) plus is probably best value as cans of even good stuff like Carny work out cheaper then endless Felix sachets and when you're feeding 6-10+ cats and are not a millionaire, Lily's kitchen and Wild Freedom is a step too far. Some will only eat dry food, which can be fine as long as they get enough moisture. Can also be very convenient and cost effective, even if the food looks expensive, because they don't need much and can be left out pretty much permanently.
Beds and toys vary too. Rule of thumb is that the more you spend and the nicer it looks in your living room, the more likely the cat will go nowhere near it. Tatty cardboard boxes, old shoe laces, ping pong balls and slithers of paper are most popular. They will show you what they like as they settle in.
When you meet the kitten, they may or may not come to you. Dreamies often help. If you want to approach them, let them sniff your hand before you touch them. It helps them check you out.
Don't be surprised if the kitten doesn't want to 'perform' for you. I've started timing visits to avoid 'nap time' (seriously) because it helps no-one if someone wants to play with a kitten who has just settled down for a good snooze.
We have basic open litter trays and Catsan cat litter from Costco. I'd like the closed trays with the top opener because I spend a lot of time sweeping and vacuuming split litter, but the little kittens can't get out of them. I've seen litter trays installed in cupboards etc on places like Ikea hacks, so I need to investigate this as a way of controlling the spread.
Are you just looking to get 1 kitten and is he currently on his own? At that age and up to about 4 months, most of them like a littermate/similar aged kitten to play with and snuggle up to. We don't generally home single kittens under about 4/5 months unless they have shown themselves to be independent/antisocial and if people only want one cat, steer them towards slightly older ones unless someone already has a young cat that they want a friend for.
