That is such good news, SC, brilliant!
I added a weaning tag for your question about weaning him. Some kittens just want to hang on to the bottle. Are you putting it in a very shallow dish or plate for him? There’s no right or wrong time but of course you’d like him to take to it asap so you can get some sleep π The weaning threads have some very good advice.
He probably doesn’t need much water if you’re still feeding him formula and wet food. Just keep putting it out for him and maybe one day he will actually drink some (more probably play with it, lol). Some cats prefer boiled cooled water (gets rid of the chlorine taste from the tap), some prefer rain water (no chlorine) and some prefer moving water. You can get a moving water fountain for him eventually if you like — meantime see what he does when the faucet’s turned on π
I’d go by his body weight, not by his chronological age. His tummy will be as small as the rest of him at the moment. But if he’s sleeping through the night fine, I’d grab the sleep while you can! If you get woken by cat crying, you will know he needs a feed.
Many TDKers swear by Cat Attract and Kitten Attract (sadly, we don’t have it here in NZ). As long as you get a non-clumping litter (cause most kittens eat their litter and you don’t want it to clump in his stomach), and most kittens prefer one without strong scents, then you can sprinkle some Cat or Kitten Attract over the top of it (because it is a bit pricey) and it seems to work fine.
Please smooch little Malfoy for me π
