I think Im adopting a baby wabbit tomorrow uwu. Any tips on how to take care of a bunny o...

I had mine two years ago.
He leaves as a cat with litter and all, doesn't go eating everything he finds (apart from my blanket........ --') he likes to olay and got used to travel in cars. He plays with cats when he stays at my mom's home but he's shy and hates other people entering my place until he gets used to them.
If you give her love, the rest comes easily.
And since it's my only companion, I haven't got any issues with the mating season thing.

i think you should do some research first before immediately adopting one

because i don't think mangago is the best place to get advice on how to take care of a rabbit

Trust me, I asked here on what I'll do after getting braces and they helped me out so damn hard.

At what time do I need to clean her poopy butt? Since I've already know they don't really bathe that much.

Basically hygiene is the only thing I lack knowledge off wid dem

2times per weeks minimum if it's wood chips (not sure it's the name) . But get her used to cat litter as soon as you can, it will be better for her (wood chips doesn't absorb at all and it can burn their skin, it happened to mine). And personnally, my lil bit likes cat litter way better he becomes crazy way I change it and all.

And if you want her to live as a cat in your house, do it step by steps.

Err. Now I'm re-reading your question...
You mean bath her ? There's no need at all if you change it to cat litter since she will stay dry. They don't need us to help them at all.

And if you adopt her from a petshop, get her to the vet and ask for scabies. They are really fragiles animals and since they're kept all together, it might declare some times after.
