Today I was talking to Katrin about Ike's sensitive feet - and the fact that he hates booties. She mentioned that she recently bought some Musher's Secret and maybe I should try it.
On the way home from class I stopped at Coolen's (my local pet supply shop) to pick up some guinea pig bedding. And guess what?! It just so happens that Coolen's carries the small size! I bought some and applied it to Ike's paws (and Bug's front paws). Ike just got back from a long walk - no paw lifting or other foot related issues. Hooray!
