a couple of years ago my cat was treated with the flea and tick drops and consequently suffered servere muscle tremors. our vet bills were outrageous. just recently i came home to find my rommate’s cat acting very strangely and his tail was twitching. i immediately regonized the symptoms and saw that the back of his neck was damp so i washed him quickly with dish soap. He has recovered fully, but he may not have if i had not had the prior experience and recognized the effects. I have now made it a priority to get the product of the shelves here in norman. March 2006 seems much too far away!!!
