Fasb is eating fine at the moment - much better than the previous six months. Been feeding him his regular kibble + a small amount of usual moist food smeared on top of kibble to entice him). Had tried a few other moist foods for flavoring, but he's having some stomach issues I thought were probably due to the new food).
Interestingly, we've discovered that feeding him 2 x 1/4 cup for each meal is better than feeding him 1/2 cup. He'll sometimes pick at the first 1/4 cup, but once he eats that, is ready for more and devours the second 1/4 cup immediately. Basically, he sometimes picks at his food like he's not interested, but once he gets going and eats more than a few bites, he's fine,
We've also noticed that, if he doesn't want to eat, we can pick up the cup of food, give him something a little different, then put the first cup back down after he eats the second and he'll devour it. He also seems to prefer fresh moist food to something that's been in the fridge, but we don't give him a lot of moist at one time, and it's not practical to open a fresh can every meal (wasting it). I throw out most cans well before they are empty anyway. Don't want them open very long.
He is having intermittent stomach issues. Nothing too serious, but it's not quite going away either. Once a week or so, he coughs up some phlegm - basically coughs up a small bit of spittle. Phlegm is yellow/bright yellow in color, which is usually a sign grass is upsetting his stomach. Doesn't do this a lot, but has been doing it once a week approx. for the past month.
He's also had some soft stool. Again, not routinely. Once every 5-7 days. Not extremely soft. Not formless or pudding-like, but a little softer than usual. Usually, he's fine next time to has a bowel movement. Good for a few days, then I notice it again.
Doesn't appear sick otherwise. Pretty normal. Eating eagerly right now. I had thought the stomach issues were due to the new food, but now not sure. Could be eating grass (he's trying to do a lot of that lately) or could be something else. Vet isn't too concerned. He's had bloodwork and tests done lately, so it likely isn't kidneys or anything else severe. Fecal check didn't turn up parasites. We've been looking for signs of worms, but not seen anything, so probably not that either. All in all, he seems pretty normal.
Little things are just concerning me a bit.
