We've been battling a nasty flea infestation for a couple of weeks with not much luck. We get rid of them, and then they just come right back. I ended up having to take one of my kitties to the vet yesterday, her abdomen was distended and looked pretty nasty. Turns out the fleas are causing a protein deficiency which is causing fluid to build up in her abdominal cavity. We think we caught it pretty early, but I'm going nuts waiting for the vet to call me back with the results of the blood work done. My poor cat looks so miserable with her belly flopping all over the place and fur that only covers her head and tail. (Flea allergy dermatitis and the protein deficiency are causing that) The main concern right now is the damage that this could cause her liver and kidneys, but like I said, we hope we caught it in time. Any one else had to deal with a protein deficiency? Or a massive flea infestation, in which case, could I get some tips? We've bombed the house, treated that cats with both Capstar and Frontline (twice on the Frontline and soon to be twice on the Capstar) and now we picked up this spray stuff from the vets. I never realized that fleas could get out of hand so quickly.
