Often, people think their Sugar Glider is going to die because it has diarrhea, is making odd noises, or maybe isn't eating as much as usual. Granted, there could be a real problem with your Suggie, it's more likely to be nothing rather than a killer disease. Before calling 911 for your little Suggie, take into consideration of what you've fed jim.
Perhaps he's ate watermelon a few times this week, well, this causes their poo to be more watery than usual, or maybe he's ate a little more protein than usual making him a little constipated. There's a number of small things that could be wrong with your little baby, and there's a number of inexpensive possible solutions.
If he's having digestive problems, replace his water with diluted NO SUGAR ADDED apple juice. If you're not sure if your apple juice has added sugar, run into Walmart, head to the baby food isle, and grab some Gerber Apple Juice. Your diluted apple juice (meaning half water, half juice) is only good for that one night and you shouldn't treat him with this more than once every so often.
If he hasn't been eating as much usual, think about how much he's ate in the last week or so. If he seems to have eaten a lot, he's probably just not hungry.
If ANY problem persists over a week you should make sure that you find a CERTIFIED vet that is an expert on Sugar Gliders.
