our cat in pooping on the bed and straining. He had crystals

This answer was rated:

our cat in pooping on the bed and straining. He had crystals before bujt has been eating uriso medical food. He seems fine otherwise but I am scared the crystals have come back. What is the most inexpensive way for us to tell?


Is Leo unable to urinate? Or is he constipated?

when did you last see him void?



Customer: replied 3 years ago.

He is able to urinate. I am not sure when he went last as we have 3 cats. He seems to be constipated because he grunts while having a stool and wants to do it on the bed but when I see him scratching I force him in the litter box. Then he goes there instead of on the bed.


Thanks so much for your reply! I was really worried when I thought Leo could not urinate because that is a MEDICAL EMERGENCY! So please be absolutely sure he is urinating.

Constipation is much less serious and we can work with that.

First, you want to feed canned food only, no dry.

Pumpkin is a good idea IF he likes it and will eat it. Other choices are baby food sweet potatoes, metimucil, whole milk because it is a natural laxative:

You can try any ONE of these (not all at the same time).

An ounce of milk as that is a natural laxative

A half tsp of olive, fish or mineral oil. If you put some on his foot she may
lick it off.

A tsp of canned pumpkin (not pie filling).

milk of magnesia or metimucil DOSAGE HERE:

An infant glycerin (only) suppository

Feed canned food with some warm water added.

Massage him tummy to stimulate blood flow and get things moving

For your other question, an ultrasound can diagnose stones in the bladder. A special diet can minimize of prevent them BUT it MUST be wet food.

Please let me know what happens and how Leo is doing

Since he is having a lot of trouble I would now give an ounce or two of milk. That should produce a BM within two hours.

If you still have questions or I can help in any way just press reply and I will be here for you.

Very fondly,
