Kitten and going to the bathroom

My 12 week old kitten has been going #2 fine until yesterday. Actually she hasn't gone since yesterday morning. Is that normal? How often should she go? I just think it is wired that she hasn't gone since yesterday morning. She is eating fine, playing and peeing. Should I be worried and call the vet?

Not yet in my view, but if she doesn't go in anotehr 24 hours I'd give the vet a phone call.

BTW has she got the litter tray habit properly now?  Hope so!

AS they get older they do go less, until many adult cats go only once a day. I have one who often goes only every 48 hours! So missing a day is no big deal. If she stops eating or drinking, or shows any distress, then a vet call is right, or if it goes over 2 days, IMHO.

She finally went and yes she has mastered the litter box.  We still have the 2 boxes but it works for her.  Not sure if I'll ever get rid of the 2nd one.  I think she only goes it in when she absolutely has to.  She seemed fine--ate, played, drank (I think), ran around, and drove me nuts.  So I knew she was ok but just started to worry.  Thank you all for your input.
