I recently moved into a mobile home that used to belong to my sister-in-law. She didn’t have her dogs on any structured flea treatment and when they moved out the fleas stayed behind. The trailer was completely infested when we moved in and I refused to move our 2 cats in until the place had been bombed. After it seemed like the problem had been resolved, I brought the cats in. I noticed that they were beginning to scratch a little more often than usual, and within the last two months the problem has gotten completely out of hand. I believe it was partially due to a litter of orphan kittens we found outside and kept in the house until they were big enough to find homes. The runt of the litter had fleas so bad that ultimately I think they were a big factor in her death. I went to Target and bought cheap flea drops for both of them, I’m now ashamed to say. I’m pretty sure they were Hartz brand, but I’m not 100% positive. I remember they came in a white and purple box. I applied the medicine to my 3 year old tabby Geneva first, and may have missed the center of her shoulder blades by a centimeter or less but it still seemed like it was out of her reach. Next I applied it to our 2 year old orange tabby Kiki. I went to check on Geneva and she made a disgusted face and ran from me and I could tell that she must have somehow ingested some. I chased her around my son’s bedroom and finally she stopped and crawled under the covers on his bed. I approached her and pulled the covers back to find she was foaming at the mouth and there was a pile of foam on the sheets. I freaked and rushed her to the 24 hour animal emergency room where they determined she was fine except for a strange fever and gave her a bath to wash off any remnants of the flea drops. The vet told me that when they bathed her she was covered in fleas, especially around her face. Our other cat Kiki had no problem with the medication. It has been about a month since their treatment and I have noticed that Geneva is beginning to look unhealthy. She scratches furiously all the time, she’s losing weight and the fur around her neck has become short, thin and coarse. I couldn’t take seeing her in such misery any longer and about an hour ago I bathed her in Sergeant’s Gold Flea & Tick Shampoo for Cats and Kittens. I’ve never bathed a full grown cat before and doing it by myself I found to be extremely difficult. I’m not even sure I used the best method, I just did the best I could. As was rinsing the shampoo out of her fur I was shocked by just how bad her flea infestation was. They were crawling into her eyes nose and mouth and I tried to pick off as many as I could, crying as she looked up at me soaking wet and completely pathetic. I dried her as much as she would allow before she finally escaped from me and hid but she was still a little damp and won’t stop licking herself. Her demeanor seems to have improved actually, but I looked around online to make sure her licking herself wouldn’t harm her. I was alarmed and disgusted when I discovered just how dangerous the Hartz and Sergeant’s products are. Several people talked about waking up the next day after bathing their cats with the product to find them vomiting blood and other horrible things. Now I am absolutely terrified that I may not have rinsed it all out and that she is going to get hurt. This cat is my angel! Should I wash it off or take her to the vet? She seems happier and is itching less but I don’t want to take a chance. What should I do???
