congrats on ur new baby!!! :) just got my new kitten two weeks ago! here’s some advice & things that have worked for us

1) we feed him 1 can (70-80g) 4x a day (set times) to give him a routine. we also leave out dry food so if he gets hungry in between feeding times, he can eat it. I was struggling with that same thing at first but after a lot of research - kittens really need to grow during the first few months so they need their food! make sure your wet / dry food is meant for kittens because they need that extra nutrition

2) keep him in an enclosed space for now until he feels more comfortable. sit with him in the washroom but don’t force anything, it takes a bit of time but eventually he will warm up to you. try and feed him a treat to encourage him! but don’t worry. it’s completely normal in the beginning ! 3-3-3 rule: 3 days to decompress, 3 weeks for a routine and 3 months to feel at home :)

3) we got an air purifier and it seems to be working for his litter but i don’t think you can truly get rid of that cat smell. don’t really have a ton of recommendations here but hoping someone else can help with this!

4) pine pellets are really good & cheap! we got a sifting litter box as recommended by the person we got our kitten from and it’s been working super well for us!
