Pet's info: Cat | Domestic Shorthair | Female | spayed | 9 years and 1 month old | 9 lbs

Hi there! Can a kitty still have giardia or coccidia even if they don't have diarrhea ? Her stools are formed , somtimes on the soft side but not always . There is mucous and occasional blood. Sometimes towards the end it's more soft in Which case she'll scoot on the floor and then lick ( could that be bad for her ??) What else should I look out for ? ( she had two recent negative fecal tests but I read that they can sometimes be false negatives ?) thank you

Yes, they can have Giardia or coccidia without any signs of disease and it can be missed by the lab depending on the test. There are a few different possibilities with what you are describing though. It could be a parasitic infection, but could also be a bacterial infection, or colitis due to an adverse food reaction. Considering you are seeing blood, it's best to have your vet recheck her. They will help to narrow-down the cause of this and provide the necessary treatment. I hope that helps and Kitty gets better soon.
