Kitten Just Pooped Out a Big String

Hello:

I posted here the other day about my kitten. I thought he had diarrhea due to me switching his food the other day, but I just cleaned the litter box and there was a long piece of something in it. Basically, I can only describe it as the twisted paper handle of a paper shopping bag. He's playing, eating and drinking just fine. Should I call the vet in the morning?

Thanks!

Sounds like he's good, but it wouldn't hurt to give them a call.

How is he now?  Still good?  I tell you, kittens can quickly get into so many things that they shouldn't .  It's very worrisome.

Hope he's not getting into too much mischief.
