Dear KayAnn, I started off by reading your frightening first post, but by the end was SO relieved to read that the beautiful Simba was getting back to normal. My first thought too, was that something had spooked him, or that he was just feeling under the weather from either the fleas, the treatment, or such. It is so scary when they just stop acting like their normal selves. Unfortunately, they just can't tell us, "I'm scared." "I don't like the company." Or, "I'm just feeling icky." Hope Simab continues to perk up. He sure looked precious, and perky enjoying his peanut butter Love to you and Simba, the Wonder Dog!!
