Well Oscar is not vomiting and shaking anymore. But both Oscar and Annie seem to scratching an awful lot more than usual. No bumps. Just scratching their ears and chewing their paws. I was giving them the recommended dosage spread out twice daily (since I work full-time.) Perhaps next month during their five-day treatment they will resond better. I don't know. It's just so frustrating to watch them and know I've made them uncomfortable...even though I know it's for the greater good. But then again, heck, if I have to deal with the die-off, so should they, right? Thanks for your tips on the grass and dosage. It was much appreciated!
