When i first cleaned Porridges cage out i found all four corners covered in crust!
The previous owner must have been useless at cleaning out
So now i make sure to sopt clean every couple of days. But i'm defintely goin to try some sort of potty with Porridges to see what he thinks.
I'll use the white vinegar aswell, thanks suga!
To answer your question Smysha, no it is not necessary i have never potty trained any hamster, although i o find it benificial to have some sort of sand tray for my dwarf.
For my syrian i spot clean and put potty litter in the corners for xtra absorbancy.
Keep an eye on her hoard and check whether it is the same corner she pees in if so then be sure to remove some of the old store oten (although you should do this anyway)
Porridge uses seperate corners but some hamsters don't
Silly billies
