Okay all have a problem here. Ferrets, Rabbits
From the info I have found it says the 32 oz is for ferrets, rabbits and other bigger pets.
And the 16 oz says for Chinchillas, Ferrets, Guinea Pigs, Pet Rats.

So I am thinking that maybe the tube size might be different too not just the bottle size.

So wanted to see what you all know about this.

Also can AFS have the same size as regular rats? Or should I get a hamster size one?

I would appreciate help on this as I need to get these ordered so that I can try to get my rats soon.

Thanks rhsm
