Cats throwing up stomach bile some mornings
TLDR; 2 adult males have started throwing up stomach bile overnight sometimes. (Could be the same cat throwing up, we’re not sure) Both are close to being overweight so I’m looking for a low calorie but filling treat/food option to give them around 8pm to hopefully keep their bellies full overnight until breakfast!
I have 2 adult male littermates (turn 5 next month) who have eaten on the same schedule their whole adult life: breakfast around 7-8am and dinner around 5:30-6:30pm. In the last month or so, occasionally one of them (we’re honestly not sure who) has thrown up stomach bile sometime overnight, between dinner and breakfast. It’s not every morning, and not even dependent on whether they have an earlier dinner and a later breakfast. It only happens some days, but consistent enough for me to want to change something for them.
They each eat 1/4 cup of dry food in the morning and 1/2 a 5.5 ounce can of wet food at night, with some Greenies on top of each meal.
My dog used to have the same issue and her vet said she should have an extra snack around bedtime, so she gets an extra treat at 8pm and that has helped her. She’s always been a healthy weight.
The issue is my cats are on the line of being considered overweight, so I don’t want them eating a ton of extra calories because they’re having trouble staying full between dinner and breakfast, but of course I also don’t want them so hungry they’re throwing up. We’ve tried putting a few extra treats in with their dinner (either Temptations or Open Farm Kitty Cubes) but it only helps sometimes.
Does anyone have any suggestions for a low calorie but filling treat that I could try giving them around 8pm, when my dog gets her bedtime snack too?
