[Dannelle D]

I gave Comfortis to my six year old cat for the first time in April. Just last week, a week or two after his second dose of it, he died suddenly. Before that, he was in good health, having seen a vet back in March for a bladder infection. Googling information on Comfortis brings up many websites mentioning a great many deaths linked to the flea medication. I would not give this to any pet ever again.
