They don't touch their rawhide. I don't know why - what kind do you give 'em? Like, what shape?
Well, I'm currently giving them three different kinds of rawhide.

Their favourite kind are the ball shaped ones, a bit smaller than a tennis ball, made of compressed rawhide.

The kind they like second best is a thick ring in a heart shape made of compressed rawhide. It has a coating that is supposed to make it taste like honey (I tried it, it does not taste a thing like honey lol)

And the other kind that probably works out their teeth the most, are called rawhide chips. They are flat and round, and about the size of a potato chip that we might eat..It is just regular rawhide, not compressed.

What kind are you giving your rats now?

PS if you find a kind like the stuff I give mine, and the rats enjoy it, then a good thing to do (that probably makes my rats mad at me lol) is to tie it to the roof of their cage so it's hanging, and they will have to stand to get at it. It provides a challenge and will stimulate their brains, and give their body a workout.

It only takes my rats about 20 minutes to chew around the place where it's hanging, take it down and move it into their boxes where they eat the rest of it
