hi. i was writting to warn you to never use hartz products. my kitten almost died lastnight.my husband and i went out to eat lastnight thinking our 6 month old kitten would ba safe at home but when we came home she was shaking and having ceasers her pupils were dialated and she was throwing up. she couldnt even do simple things such as walk or jump up on to her favorite spot on the couch. we rushed her to the emergency vet they hooked her up to an iv gave her a bath and gave her a shot of vallum. she left the vet with a pocket full of water a little pouch on her back. she is still a little wobbily but she is eating now. i urge you to never use hartz it could leave temporary permanate damage or even death. too bad they dont put that warning on their products.
