Why is my cat straining with bloody diarrhea after tapeworm meds?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Longhair | Female | spayed | 11 years and 10 months old | 10 lbs

I have been treating my cat for tapeworm with Homeopet feline worm clear over the past couple of weeks. Today she started having trouble passing her stool dragging her back legs a couple of times. She tried a few times passing only minute amounts of diarrea, where I also noticed some red blood.

Poor girl. It sounds like she may have a bout of colitis (inflamed colon) which is common following a tapeworm infection. You can try treating her with probiotics, Culturelle over the counter, to see if this clears things up. You can also try adding in 1-2 tsp of canned pumpkin (not the pie filling) in her food daily to add fiber and help bulk up her stools. I would also recommend feeding her a bland diet of boiled plain chicken or tuna and white rice for about 7 days, and then slowly transitioning her back to her normal diet. If her diarrhea and straining does not improve within 3-4 days, then its best to take her to your vet who can test her stool and make sure there isn't something else going on. If it is just a bad case of colitis, then a short course of antibiotics will likely resolve things. Best wishes with Stockings and I hope she feels better soon. Take care.
