hello! did you ever determine whether the lack of coordination was from the Atopica? My cat has been on it for about a week for an autoimmune problem with his liver and he is wobbly in his back legs! My vet doesnt seem to be concerned about it and reluctant to say its from the medication, but thats when this all started.
Her vet thinks she acquired a bacteria called bartenella. This caused all of her problems... lameness, fever, joint pain, respiratory complications and since it was not caught in a timely fashion, it damaged her heart and she now has a heart murmur.
She has been on atopica for about 2 years now (she takes the pill form, not liquid) and the biggest side effect is the upset stomach.
