That looks like it was designed with Betty in mind! Which color will you choose? And check out that sunflower scratcher on the bottom of the page! Probably geared/sized more for kittens, but I like it. A lot.This looks like a good starter option for her until I find something else.

Cats can be very hard to guesstimate as to age. Just praying and hoping for Betty to thrive and have good health!!!
