Question

What does it mean when if my guinea pigs poo is really small when its not supposed to be?

Answer 1

maybe he isn't eating a lot right now, probably you should offer some different types of food to see if he will eat more, if there isn't any change in appetite there could be a more serious problem that a vet should diagnose.

Answer 2

It might  be sick.

Answer 3

Not eating enough, maybe its still a baby, sign of an illness.
