Is feeding my dwarf hamster with salt saturated foods a good idea? Will she pee a lot?

They should get enough salt from their diet, so she's most likely getting way too much. Humans are much bigger (!) therefore we can process a lot more salt, therefore there is more in our food. Dwarf breeds are way smaller (again, !) so they don't need and can't process as much salt as we can, so it shouldn't be in their food.

Is her "crotch" yellow and "soaked in pee" constantly? It could be a serious condition.

Stop feeding her so much salt. Dwarf breeds are from semi-desert areas and instinctively limit the amount of water they drink by themselves. If you have her out of the cage constantly, of course she's gonna pee everywhere.

I don't think a LOT of salt is good for ANY living creature. You have to feed a balanced and nutritious variety.

i have a dwarf hamster my self i feed my one hamster food mix some times a tiny bite of carrot they will also eat biscut just a half thats all you should feed it.

Just limit what you give him

if its peeing just limit its water supply
