I just got a one month old rabbit yesterday. I initially fed her hay and a little carrot last night and gave her water. She pooped and peed after but she hasn't pooped since then! Today i fed her the same thing, carrots and hay. and added some rabbit pellets and also water. she peed 2 times today as far as i noticed but she hasn't pooped since last night. what should i do?! she doesn't look sick at all but it worries me because she hasn't pooped since last night. she still eats and drinks. and she's still quite active. please help!
