My guinea pig doesn’t week, he also doesn’t like hay

[Puinea gigs]

Hi I have 5 piggies but Mochi ( the pig that I am worried about) lives on his own he hqs never made a sound and also doesn’t eat a lot of hay at all. I am worried as his poops are abnormal and they have been for quite a while. I hope someone can help with my problem, thanks

I would recommend that you take him to a vet for examination.

A vet is the only person who can diagnose any issues.

Does he live alongside the other piggies?

Do you weigh him weekly as part of routine care? If so, how has his weight been - stable, losing etc?
Can you explain how his poops are abnormal please? if they are soft or misshapen, then it can be because of a digestive upset. The normal course of action in such a case is to remove veg from the diet and feed only hay (and the normal limited amount of pellets), and give a probiotic to see if things stabilise. If they don’t then it’s best to take piggy to a vet.

Hay is essential for gut and dental health. His weight checks are the way to know he is eating enough hay.
Have you tried different hays or tried a different way of feeding it (ie if you use hayracks, try just putting hay loose on the cage floor instead - I always find they eat so much more when they have it loose).
