The cat is 11 or 12 years old, and I got him from a friend two years ago. He's been very healthy all along until the last few weeks, when he seemed to be losing some weight and being annoyed at our other cat. He is still eating his food, but apparently not as much as before. I've started to monitor his bowel movements, and have noticed a fair amount of clear mucus when he poops, but no blood. The poops themselves are brown and normal-looking. He does not seem to have either diarrhea or constipation and doesn't seem to be in pain, although maybe has some discomfort since he wants nothing to do with the other cat. He just isn't quite his normal self.
His food is canned cat food (Friskies). I was also leaving out dry kibble but will just go with canned now.
Does anyone have any similar experience with their cat having a lot of mucus in the stool? Any tips, vet histories, etc.? The vet is a long expensive trip away, and with covid around I'm very reluctant to risk a trip. I'm hoping this is something that will abate with time, but any feedback will be welcome.
