Hi. My 13-yo male has been having issues with bowel movements, and he recently lost a noticeable amount of weight. I noticed the weight loss first, but then he pooped in the tub one day, and there was some blood and mucus in his stool. I took him to the vet, he had a senior panel and rectal exam, and I brought a stool sample. They found absolutely nothing. He is about 2 lbs lighter than what's normal for him. We were sent home with some metronidazole, which is almost impossible to give him (I guess the taste is awful, so I've been mixing it in his food).
The bright red blood is gone, but his stool is still off-color with some mucus. It doesn't look blood-tinged like it used to, but it's still kind of a light rusty color. Last night, just the liquid came out, and then he strained a light-colored poop somewhere else. And I found more of the liquid in the tub this morning (haven't found more poop yet), and he just vomited a bit.
Any ideas? I was hoping they'd find something easily treatable in his labs, but finding nothing at all seems weird. No new stress that I can think of. I did pick up a new bag of his usual food sometime before all of this, but I can't recall how close to these symptoms. However, I don't think he's really been eating as much as he normally would. I have another cat, so it's hard to tell which one ate how much.
