Congrats on coming to the real side breh
Ive rescued a few feral kittens. It can be a little exhausting having to hand feed it now but stay on it. Its important that they get fed every 4-6 hours. Theres kitten formula at the store. Try petsmart.
Its pretty easy to potty train them. Start off with a small tray with litter. Something they can easily climb in to. Most of the kittens ive had didnt need to be told. Its something in their dna that tells them to shyt on the litter
Once you get her weened and potty trained youll be able to enjoy it much more.
I'm going to craft one out of the lids of old sneaker boxes. I got her Saturday, and she was pretty weak, still crawling short distances. Now she's starting to zoom and doesn't want to be held when being fed. She'll run, explore, come whine to be fed, repeat. But even though she's getting stronger, I don't think she'll get in the small box I got her without tipping it over.
