PLEASE PLEASE PLEASE do not use flea drops on your cat or dog. My sister put Sergeants Flea drops on her cat and she is no longer with us. She had many of the same symptoms as stated by other pet owners such as vomiting, loss of appetite, seizures etc…. She was perfectly fine beforehand. It’s a horrible outrage that these products still continue on store shelves. We’ve learned a hard lesson and encourage others to please find alternatives to flea control. Gumdrop was a big part of our lives and is sorely missed.
