Hamster Fact: Hamsters are very hardy animals but they do get sick from time to time. One illness that is treatable is an impacted pouch. Most hamster parents give a health check to their hams when they pick them up everynight, and this is one of those things to look out for. When a pouch looks like it has been full for days then you might want to go to the vets to have the pouch flushed. Food may have gotten caught in a crevice and could be festering. This can lead to infection in the pouch and pain for your hamster. Sometimes the vet will turn the pouch inside out and flush it with water and most likely perscribe antibiotics for your little guy. So check those pouches!
