sometimes a little olive oil helps-and with furballs too
--Mimi

canned pumpkin (not pie filling) helps.  So does yogurt.
Just be careful that the kitty is urinating.  If perchance he's blocked and
not constipated, it could be deadly.

I would try mineral oil mixed in the cat food, it's worked for me.

Good Luck

Constipation is usually a symptom of something else (e.g., hairballs,
dehydration, potassium depletion).  Also, a disorder in the anus or rectum
that causes painful defecation can lead to voluntary fecal retention - which
in turn leads to constipation.

The longer feces remain in the colon the drier and harder they become and
more difficult to pass - which tends to become self-?perpetuating -- leading
to continued voluntary fecal retention.

I suggest a trip to the vet to find the cause.

I would definitely have him checked out by a vet, because constipation
could be a symptom of something more serious, such as megacolon.

See if he likes canned pumpkin.  One of mine loves it, and the other
isn't interested.  You can mix it with his food, if he isn't interested
in it plain.  It's high in fiber.

Hairball remedies, like Petro-Malt and Laxatone, can also be helpful as
a lubricant for constipation.   They are basically flavored petroleum
jelly, and if they don't appeal to the cat, you can smear a dab of
Vaseline on the top of his front paw and lower leg, and he'll lick
it off.

Of note, shortly before Gideon's bladder stones were diagnosed,
I thought he was constipated, because he would sometimes go in the
litterbox and apparently try to poop, and leave without doing so.
The vet said that the bladder stones were making it painful when he
beared down to defecate.
