About 3 months ago I adopted a cat who had been abandoned in my apartment building. She seemed completely healthy and was fine for the first month of owning her. In the past month I've experienced three occasions where she has had a small amount of blood in her poop. The stools are typically a little softer (not diarrhea) with a little bit of blood. She poops about one or twice a day and it seems every 7 days or so she has had a bloody stool in the past three weeks. She's eating normally, drinking water, and is very energetic but it's still concerning. I'm definitely going to switch her food and see if anything improves but a lot of websites have been saying that it could be an infection/parasite so I am a little concerned. I don't want to rush to take her to the vet since the tests are crazy expensive and she doesn't seem to be in any pain. Does anyone have any advice on what could be wrong? Should I be worried?
