Hi, One of my girls is more gut sensitive than my youngest one and so I would like to feed them separate giving them the same diet but different ingredients. How would I do this since they eat all night...???

You could offer both of them something different. The only other way would be to put them in separate cages at night.

I guess the challenge is I normally put one dish for both of them and they just eat away all night. How do I make one eat only one of the 2 meals if they are both living together. I don't see myself putting them apart all night when it is the only time they get to hangout and play with each other.

Have you considered offering only the foods that the sensitive-bellied glider can eat? As long as you make sure you're providing adequate nutrition.

Fair enough, I did a new batch of food and so hoepfuly this one feels better for both! Im on TPG and so it asks for 1 cup of yogurt which I now susstituted with vegan coconut yogurt... anyways we'll see thanks!
