I think my boyfriend is allergic to my baby guinea pig (or his bedding, or the timothy hay). I found that PetSmart sells Brown's Falfa Cravins Timothy Hay Tidbits (link:
Brown's Falfa Cravins™ Timothy Hay TidBits - Hay - Small Pet - PetSmart)
Is that a nutritional substitute, or should I stick to feeding him regular timothy hay? Thanks!!!
