Any idea when this will be available again?
Answer by Cris • Feb 25, 2022
So I went online (not through the app) and they have different size bag options there. I was able to order it that way. Hope this helps.
I have one cat who has been prescribed this food. Is it safe for my other cat who has no issues? He is male and I worry. Unfortunately they have grown up eating with each other and it's extremely difficult feeding them separately. Thank you!
Answer by • May 28, 2019
As this is a prescription food formulated to meet specific diet restrictions from known health issues, this food should not be fed to any other animal than the one prescribed due to the restriction of specific nutrients. Prescription diets can be detrimental to an otherwise healthy pet if that pet doesn't have the ailment for which the food is designed.
Is this food for cats with IBD and Oxalate crystals?
Answer by • Sep 26, 2017
This food is formulated with low molecular weight peptides to support skin and digestive health in cats with food sensitivities. It also prevents the development of both struvite and calcium oxalate crystals that form urinary tract stones.
What is in the natural flavors?
Answer by • Jan 12, 2021
The natural flavorings come from the ingredients themselves along with the fats and oils.
