My cat is constipated with soft stool and straining. What's wrong?

Updated On September 23rd, 2025

Pet's info: Cat | Turkish Angora | Female | spayed | 18 years and 1 month old | 5 lbs

See bio for complete information. Marshmellow had been having constipation issues. Currently I know for a fact there is no blockage, the stool is soft, it is read to go all the way to the rectum in the colon, she is trying to go but can't. No megacolon. I just had her in yesterday. This is really really bothering Marshmellow and it is effecting her recovery by making her not want to eat. She drinks tons of water. She is urinating. I am clueless. She has been on miralax, no help. Lactulose now.

Have you tried a diet change? You can change to intestinal formula or hypoallergenic formula to help. Canned food would be ideal as it has a higher water content to help. Have you or your vet consider a prokinetic (metoclopramide or cisapride) to help the intestines keep things moving to help her go? You may need an ultrasound to see the thickness and look inside the intestines or consider a biopsy if getting no answers or help with medications.
