Just got back from the vet with my 9 yr old male who has crystals in his urine. The vet said it is due to diet being too high in calcium. He is on instant HPW with mixed veggies and blended fruits. The vet advises to get "smart HPW". What other diets are there that have lower calcium? Or I guess anything to offset the amount of calcium he gets (along with the other 3 gliders with him)

Are you feeding the HPW from Exotic Nutrition?
I would recommend BLM, OHPW or TPG for diets.

I am feeding the one from exotic nutrition. I used to feed the BML. But one of my gliders stopped eating it completely so i switched to the instand HPW. (Which I believed to be ok) I asked my vet what her opinion was on the BML diet to which she said it was still too calcium heavy and the batches of food cant be regulated to make sure that youre not feeding too much calcium. I bought the OHPW supplements to try. (Fingers crossed that all the gliders enjoy it). The smart HPW that was recommended by the vet I cant seem to find the ingredients or even how much comes in a bag. Didn't know if there was any opinion on that diet.
Im really hoping the OHPW is a hit and clears up his crystals. As well as not being too calcium heavy.

I hope that it'll be a good fit!
