I have a 5 month old kitten, Pooh Bear. He had fleas so I bought the Hartz Ultra Guard Flea and Tick spray! Well, I was spraying some on his fur, and not even 5 minutes later he was shaking, and salivating everywhere. My boyfriend came in and asked if Pooh Bear drank a whole lot of water and just forgot to swallow and spit it out everywhere, I said no he is salivating from this spray. Minutes later, the kitten was jumping around and leaping and gagging every where and moaning and just having terrible screeches. We got a dropper and dropped a lot of water down his throat to get some water in him. I gave him a water bath to get everything off of him. This didn’t help and he continued to jump around and salivate and seemed to have a minor seizure. A while later he layed down and slept, but his breathes were short and distant. I stayed up the whole night with him while he slept and woke him up every so often to make sure he was okay .His eyes were white and dazed. I thought he was dying. I ended up falling asleep and the next morning he was fine. I returned the bottle of the spray. I called hartz and explained and they said “YOUR CAT WAS HAVING A REACTION TO THE PESTICIDE” I yelled at her and said I’m 19 years old and i have more common sense than you guys, your putting pesticide in animal products!?” I’m happy Pooh Bear lived, but I told myself, if he didn’t make it, than I was going to quit my studies of a vet technician. He’s doing all better now. Walmart wasn’t to thrilled I returned it, though.
