-Reduce the size of the cage by removing the shelves.
-Let the ferret choose his corner. More than likely it will be at the far end of a cage, near a wall. This is because ferrets feel very vulnerable when going to the bathroom, and like to be in as secure a spot as possible
-Cover the bottom of the cage with old clothes or baby blankets – don’t use the carefresh stuff. Since many ferrets have been going to the bathroom on carefresh their entire lives, they won’t recognize it as bedding and not litter.
Put immovable objects in the other corners of the cage – water bottles, plushy animals, food dishes. Now the ferret has only one bathroom choice: on his bed, on his food, or in the litter box! It may seem the cage is too small, but you’re only going to keep it like that for a couple of weeks as he learns what the box is for.
-Get large triangular or rectangular litter pans. Ferrets, especially males, like to get their whole body into the box, small triangular ones don’t seem to give them the room they prefer.
-Don’t get clumping litter – it’s uncomfortable to some ferrets and in some cases dangerous!
-Put some old poops in the litter box so that he realizes what its purpose is. Don’t clean it to well, since he’ll get confused.
-Ferrets are neat animals, they won’t want to go in dirty, unkept litter boxes with poop piled inches high – keep the box clean, scooping at least once a day.
-Give treats when he goes to the bathroom in the box, even if you have to put him there.
-Ferrets will go to the bathroom within 10-20 minutes of waking up. When you see him wake up, watch him, and when he starts moving to the wrong corner, pick him up and put him in the box.
-You may have to secure the box to the side of the cage, as ferrets will want to see what’s underneath. You can do this by punching holes in the side of the box and securing it to the cage with zip ties, or using Velcro.
Litter training outside of the cage
-Remember that ferrets go to the bathroom about 10-20 minutes after waking up. Don’t let them out of the cage until they go to the bathroom. Make sure that you give them a treat when they go in the box!
-Limit the free-range area until they get the hang of it. Don’t let them have free run of the house until they have good potty habits in one room, or even ½ room.
-I once read the following analogy: when a ferret sees a litter box, he thinks to himself, “do I have to go potty?” If he does, he’ll go to the box, if not, he’ll go on his merry way. When a ferret has to go to the bathroom, he’ll look for a litter box – if he doesn’t see one, he’ll use the nearest corner, or anywhere that has a faint odor of old potty mistakes. Therefore,
-make sure you have enough litter box, visible to your little ferret’s eyes, and
make sure you thoroughly clean any mistakes
