Oxbow Natural Science Urinary Supplement is a chewable tablet supplement for small herbivores — rabbits, guinea pigs, chinchillas, and rats — where urinary health needs a little extra support beyond diet alone. It sits alongside Oxbow's broader Natural Science range and is aimed at pets prone to sludge, stones, or general urinary tract sensitivity.

The tablets are Timothy hay-based, which keeps fibre intake consistent with what small herbivores should be eating anyway. Cranberry and dandelion leaf target urinary tract function, while astragalus root supports renal health. Being hay-based and palatable, most rabbits and guinea pigs accept the tablets as a treat rather than needing to be dosed. Made in the United States by Oxbow.

Owners reach for this one when their small pet has a history of urinary issues or is heading into the senior years where kidney and bladder function tend to slide. The chewable format matters — small herbivores are notoriously hard to medicate, so a tablet they'll voluntarily eat saves a lot of stress.
