Feeding guinea pigs with too many foods can also cause stomach upset and diarrhea which can attract more flies to their cage. Furthermore, giving your cavies rotten food can attract flies to their enclosure.

This is why you should provide a good diet for your guinea pigs. You can keep your guinea pig’s digestive tracts healthy by providing plenty of hay and a high-fiber diet.
