Cat anemic after worm treatment: How long for white gums to pink up?

Updated On September 23rd, 2025

Pet's info: Cat | American Longhair | Female | unspayed | 1 year and 2 months old | 8 lbs

I took my cat Stevie to the vet for shallow breathing and to get flea prevention. The vet noticed a large amount of tapeworm segments & treated her for worms. He also said she was anemic as a result of the worms and gave her a B12 shot. Her gums and nose started to pink up again hours later but now they are both white again. I can’t afford to take her back to the vet until next week. Will this resolve on its own as the worms die? Is it normal for it to take a while? Is there anything I can do?

I am sorry to hear Stevie is not feeling well. Some gastrointestinal parasites drink blood through the intestinal wall. This will cause a patient to be anemic. However the level of anemia is important to know. IF the red blood cell count gets low enough a patient might need a blood transfusion or could pass away from this. If the red blood cell count is only slightly low and the parasites are treated over time (maybe a few weeks) the patient will recover and the anemia will resolve. I hope that helps
