I recently was given a 5-6 week old male Mookie when I went to the vet to get antibiotics for 13 month old Ziggy.

Mookie drinks the F/V 20/50 voraciously. He certainly makes Henry's block disappear, although hard to tell just how much is ingested and how much is merely reduced to tiny bits. I suspect he eats a fair bit, however, as after these were introduced he drinks somewhat less F/V.

Ziggy is a special needs squirrel, and I still give him F/V 20/50 3x daily to help balance his nutrients.
