Tidy-Cats Unscented and Non-clumping
(I recommend avoiding clumping litter and silica/crystal litter due to toxic side effects if ever eaten. Non-clumping clay litter, paper litter, and wood pellets are all fine options. Clumping clay litter is fine once you’re sure your kitten will not try to eat anything out of their litter 6+ months old..)
Kibble: Purina One Kitten / Purina One Indoor (once Adult 1 year+)
Wet: Fancy Feast Kitten Pate / Fancy Feast Pates (all flavors accepted, Fancy Feast Pate is grain free as a default which I love.)
