Cat Constipation
Megs4990 posted:
I recently adopted a cat at the local human society, I brought him home and he was very friendly, he ate, he did poop and pee on the floor( but i figured that was out of nerves) the over the next couple of days I noticed he had not been going to the bathroom at all, then one night he woke me up because he was crying in pain, shaking, and throwing up trying to poop, the next day I got him to the vet, and they could not find anything wrong, they could not even feel a backup in stool. They even ran blood work and found nothing wrong. He is an older cat, they told me 8 but the vet says it's possible he could be older. It's been a month and in all it's happened again twice. Is it possible that he is just an older cat with constipation? and is there anything I can give him that can help him? He normally eats wet food, and dry food. He also drinks water. I have read a lot on cat constipation and he has no other symptoms besides the not being able to go and throwing up after trying so hard. He has an appetite and on most days is a very outgoing cat. If anyone can give me any advice or suggestions I would greatly appreciate it!
Drew Weigner, DVM, ABVP responded:
There are two things to consider here: one is that he may be straining to urinate instead of defecate. This is simple to rule out with a urinalysis. If your veterinarian hasn't done one, it's time. The other is that he truly is constipated. If so, he should have a set of x-rays to make sure there isn't a physical blockage (such as a previously fractured pelvis.) That being said, it's not rare for older cats to have difficulty passing stool. This is often due to a decrease in motility of the colon. Sometimes adding fiber to his diet will help. Your veterinarian may also prescribe stool softeners, although cats don't like them much. Another treatment that is often highly effective is medication to increase the motility of his intestinal tract, but this must be given every day for the rest of his life. Further discussion with your veterinarian is in order.
