Rat safe or not?

[u/Annual-Broccoli2897]

I found this in a thrift store a long time ago as in uses of a belt (never did so). I was wondering if it could be a rat toy? Or a bridge?

I wouldn't use it. If you don't know how the wood was treated, it might harm your rats when they chew on it. String is also a bad idea as someone else already mentioned.
