Feeby is dealing with fleas and is being treated. Short of acting like an older cat who has never had fleas before and was initially freaking out, she is eating/drinking/peeing/pooping pretty normally. She has taken to not wanting her dry food, so she has pretty much been strictly on canned food for the past couple of weeks. However, today, she did the same thing she did a couple of weeks ago - goes to her litter box and pees a little, gets out of the box, sits by the box for a while and then goes back in and has loose stool. When this occurred two weeks ago, she leaked a bit of reddish tinged fluid outside the box - but no smell. This time, she did the same thing, but before deciding to hide, she had actually discharged a very, very small amount of red blood. Last time this happened - it was just the one incident and it was gone. However, I did take a fecal sample in for a quick look and the vet found nothing abnormal. She has had a history of UTIs, so I put her back on her usual antibiotic. Not more than 4 days later with her next vet visit, her urine tested clean, no blood/sediment/infection. I never figured out what caused that one incident on 8/9. This time, I am suspecting that it might be from her eating nothing for the past 4 days other than RC SO canned, because when I went to the store they were out of her Hill's C/D canned. Is it possible that not having other food to trade off with, and being solely on RC SO canned could cause this? Her poop has been very smelly recently, but I have not actually seen any blood in it, and until today her feces has been fairly well formed. I will add, that before the flea issue, she had lost 1.5 pounds from April to July. The questions behind this have been left unanswered, as the vet wants to clear up the flea issue first - he thinks it may have been going on a lot longer than we knew (could be?). Her bloodwork in July showed no anemia, but some of the WBC counts were a tad high. I don't know what to think.
