How often Should cats Poo?

I just noticed Trout didn't poo in the last 24 hours. She is acting normal other than that and has been peeing.

Are they like humans where sometimes they don't poop everyday?

Dori occasionally has a day where she doesn't go. It makes me worried that there is something wrong. I pay attention to that and how much food she eats on a regular basis. If Trout has been eating normally, I would give him a tablespoon of canned pumpkin. If he is a little constipated the pumpkin helps. Dori likes the pumpkin mixed in with her regular wet food. It's like a treat for her

Have you switched cat foods? I know with my crew nutro wet makes them constipated a tad bit. if shes eating same food id wait it out...give vet call in am-if its truly shes constipated milk might help but if shes not then youll get exploding cat I don't watch my cats taht close but My 16yo does have issues(easily seen when cats grunting in the box...

How'd you do with this problem? Get it cleared up? Oliver usually goes twice a day... am and pm - sometimes only once though.... occasionally he will have a day without poo, but then there's usually 3 the next day, haha
