2 of my cats will pee in the box but won't poop
I currently have four male cats, all adopted within the last 2 plus years. About a week ago I changed litter as I was really not happy with the one I was using.
I scooped it about 2-3 days later and found very little feces.
One of them (who is the latest adoption -- about a month ago) has diarrhea due only to stress (He has no problems with the other cats or my home but is still very uncomfortable with me).
Took the other three to the vet. One of them apparently pooped while in the carrier and had it all stuck in his fur so I know he is OK.
One of the others I saw once go into the box, circle, squat but nothing happened. He left but did not come back.
The last one I have not even seen try to poop. The vet said that there was no constipation and that they all looked very healthy.
They all eat (Purina One urinary health dry and a quarter of a can of Purina plus every couple of days) and drink fine. Also their personalities and activeness/socializing has not changed.
In order of mention they are 1 1/2 yrs and about 12 pounds, 4 yrs and about 11 pounds, 4 yrs and about 12 pounds, and 3 1/2 yrs and 16 pounds. I searched my whole house and found nothing (there are not many places to go for them to hide it).
The vet was confused as well. Please help if you can.
I'm stumped too, Scott. Unless there's intestinal blockage, it's got to come out some time, right?
Assuming the vet isn't missing anything, and assuming they're not constipated, then we'd have to guess stress.
Any changes (addition of a new cat), changing of litter type, and so on can induce stress. The stress can also build up and while a cat may not show it today, 2 months later... problems.
A couple of points...
1) Never go cold turkey. Always change litter slowly, adding in maybe 20 percent of the new litter to the mix to start, taking several days to change it completely.
2) Give your cats a choice, if possible. Put a litter box of the new litter mix next to the old box with 100 percent old litter, and let your cat choose which one they want to use.
3) For 4 cats, you should have 5 boxes.
4) If you're using scoopable, clumping litter, scoop at least daily.
5) The one that pooped while in the carrier... that would indicate to me that he might have been holding it because he's not happy about the new litter.
6) When one cat is stressed, they're all stressed, even if not all of them show it all at once.
Were the feces you found dry and pebble-like? That's a sign of constipation, although if you wait a couple of days to scoop, it's hard to tell sometimes.
If these were my cats, I'd be concerned about a missed health issue, but I'd start by reverting back to the old litter and watching things closely.
I might also try a mild laxative if the vet approves of that. That's my take on it.
I hope that gives you some ideas. It sounds like you're a really good cat parent and I thank you for adopting all of these little guys.
Please let us know how things turn out.
