We recently moved into a rental house and received a rather nasty surprise. The house had, evidently, previously been infested with fleas, and one good vacuuming was all it took to begin a re-infestation. We have two cats who had never had trouble with the critters. Our larger, and older cat got by with his monthly dose of anti-flea back-of-the-neck-vet-approved stuff, but our younger, smaller gray tabby was quickly overcome. We tried shampoos, powder, spray, prescription flea meds from our vet, nothing worked. He began to weaken quickly, and this morning I was afraid I might lose him. I drew up a tubful of warm water, added a little Dawn and gently eased the cat into the tub. After about ten minutes, he went limp in my arms, and I just knew he was gone. I pulled him out, wrapped him in a big, soft fluffy towel and sat down in the rocker and rocked him for the next thirty minutes. Fleas that had not shaken lose after flea shampoo, spray, powder and the prescription back-of-the-neck medicine were coming off my poor cat in droves. I changed towels and rocked him some more. Two hours later, he was a bit perkier and able to eat. It will take a while to get him back on his feet, but he's going to pull through. My husband and I've spent the better part of the evening treating the house, and all towels and bedding are getting a hot water-Dawn washing, believe me! I was skeptical when people told me Dawn worked on flea problems with weak animals...thankfully, it was true. Signed, A Thankful Pet Owner
