Reading the whole thread on this matter helped me a lot. Saved a cat living next to a KFC and after a week noticed the prolapse. Had my hands in my hair the last few weeks of what to feed her. De wormed her but will take her to vet tomorrow as she is obviously starved. Such a sweet little kitten. Seems cats living on the street is more likely to get this as their diets are terrible and exposed to parasites. Will get yogurt and pumpkin tomorrow. Hard work to keep cat and house clean. Thank youProlapse happens when there is persistent diarrhea/cramping, the pushing and inflammed tissue has noplace else to go but out.
Treating the diarrhea is number one in getting this to fix itself, and it usually does.
If dewormed and no parasites it is very likely a dietary caused diarrhea.
If you are able to feed grain free canned food, and add some pure pumpkin daily, it will greatly improve.
Don't switch kinds/brands, and to start off did the vet explain how to settle his intestines down right away with bland foods such as nothing but chicken or turkey baby food for a few days?
It is so easily digested that it allows his internals to calm down rather than continue irritating them.
Then you will slooowly reintroduce grain free canned like wellness, etc.
