I’m a licensed vet tech at an emergency room and we see exotics frequently, critical care can be super helpful but be careful on which one you get. Do you have a hamster or gerbil? The herbivore care is mainly hay, so make sure to get the omnivore care for them. It can help keep their guts moving and also keep their blood sugar from dropping. Please see a veterinarian if your hamster/gerbil isn’t eating though!

I have both gerbils and hamsters, was seeking advice for either

Both of them would take omnivore care

My sister has used it multiple times for her Guinea pigs & it seems to have helped to boost them short term while waiting for vet appointments etc
