Well... Our dogs were doing great on Frontline for quite some time.. and then this spring we had a huge flea infestation that sprang up and we are only just now getting a handle on it since I got a new flea stuff off Petmeds. I was just thinking about it last night and looked up at my little hamster. I realised I had never thought about my beloved little hamster when it came to the fleas.. and he has a very open airy cage. So do hamsters even get fleas? I can only imagine they can. Though he regularly grooms himself.. I can't tell the difference between regular grooming and itchy hamster grooming. Do I need to be worried? If so, is there something safe to use on my little boy? Thank you!
