I can imagine a few reasons.
I have a dog, she needs some running around space in our yard, so we make sure she has it.
Otherwise we do have a raspberry… Thicket? In the corner of our yard, and some smaller raised beds along the edges. Every year the local squirrels steal the veggies we plant, but not the raspberries, no matter what we do.
Yeah, it’s not the material, it’s the chewed off bits that I would be worried about. It would help you prototype something, then make a mold that you can use.
For my dog though, if it doesn’t squeak, it doesn’t exist.
