Ferret toys are not a simple matter of grabbing something, throwing it at your ferret and seeing if he enjoys playing with it. It requires a bit more thought than that, as many toys are not very safe for your ferret. You may also run out of more weekly ferret toys if you choose the wrong ones.
You should already know that ferrets lack any concept of the term restraint. If you give them something that isn’t extremely durable, ferret toys will get battered, bruised and broken in record time. If in doubt, think about whether you’d survive a fight with a baby during the “terrible twos.” If not, continue your search.
In general, I will talk about security first, but there was a point about durability that will help you understand security better. Most of the safety hazards with ferret toys consist of choking or swallowing hazards. If it’s small enough to swallow whole, avoid it. If it’s soft and gives a lot, avoid it. If you give them a rubber toy, nine times out of ten they will chew on it and may swallow parts of it.
If they can break it, it will break and then become not only a cash suck, but the pieces will also be a security hazard. This may sound simple, but you can’t be there to supervise 24/7, and even if you could, no one really wants to try the Heimlich maneuver on a ferret.
Treat your ferret as you would a baby. If you wouldn’t give it to your baby, don’t give it to your ferret. They have more or less the same mentality regarding the game, which gives you ideas both on what to avoid and what they might find interesting.
Good luck on your search for ferret toys.
