My husband just brought home a cute little kittens. She’s infested with flras, so we bought this big bottle of Dee-flea shampoo stuff. A girl who works at a pet store said we should get it. We’ve already dipped her like 4 times. The fleas don’t die, we just have to try and pick them out ourselves when the fur is wet, by our fingersor the flea comb. They just won’t go away, I feel so bad for her. We’re getting there, but is there a better way, and advice???
