I just bought some flea and tick squeeze on for dogs by a brand called Sergeant's... and luckily read up on it online before using it! Apparently something like half of the cats using Sergeant's brand flea and tick control react to it, and I see a lot of reports of animals having seizures and even deaths associated with this toxic product. Of course I will be returning it in the morning. I purchased it from a grocery store, and they also apparently sell it at WalMart. So beware this product! It makes me mad that this is on shelves...
