Toothbrush Brands and Kitty Tummy's

Those $1 packs of toothbrushes didn't work out. They had all these pretty colors and I was hopeful that since they were so cheep that they would bend okay. Didn't work out at all! So, the record is that Reach and GUM brands are the only ones that I have found that work out. If you have any suggestions on other brands, please share!

NYRP #35 and #36

P.S. The cats have the runs and I have no idea why, any one know of a healthy way to help ease their tummy's?
