Is it ok for your cat to eat a fly?

Flies are protein and fine for the occasional crunchy snack for the cat. Some flies apparently taste better than others as most cat owners know. The slow iridescent bluebottle fly is a favorite "prey" for house cats but often spit out when caught. Regular small house flies when captured are consumed and enjoyed with no ill effects on the victorious hunter. Wasps and bee's do fight back but are often mistaken as flies until the cat learns to recognize them. Praise your cat for its skill and cunning as protector of the household.

i don't think so. but it might just poop it out or throw it up.
