What’s the deal with prescription diets for pets?
This is an explanation I gave someone who queried the obvious - prescription diets for carnivorous cats are still made from grain, and even in the case of renal disease where moisture is essential, veterinarians still recommend a dry prescription diet as an “optimal” solution.
Hopefully it makes sense, as these things often don’t to many:
Commercial pet foods are products, and even prescription formulas operate within those boundaries.
To elaborate further, their primary goal is to make a profit - otherwise they wouldn’t exist - and there are a great deal of constraints in production cost from ingredients to packaging.
It made sound odd, but those products are still formulated with good intentions, to improve the health of pets with whatever health conditions they may suffer.
But they still operate within those boundaries.
It’s worth understanding “improve the health” is in relation to whatever commercial product was previously fed, which likely caused the illness in the first place, and within the confines of commercial products it isn’t that hard to offer the pet something a little better to show positive results.
For example, a cat who has suffered from a wheat-based diet will show an improvement in health when transitioned to a rice-based diet, but the overlooked question is whether either are optimal for a carnivorous species.
Facts are facts, cats are carnivores, and most kibbles substitute animal ingredients in favour of cheaper ingredients to ensure profit.
