Yes, I remember when I first researched rats (I wanted to gain as much knowledge as I could before my husband and I took the plunge to adopt) and I read several times to "always think outside the box" when it comes to toys, etc, for rats. One my books said, "Go to the cat or bird section as well as the small animal area in pet stores or when purchasing items online...cat and bird toys can make excellent toys for rats too." I never forgot that advice! Those hanging rope and wood toys for parrots are great for ratties!
