As the title suggests, everytime i see him when i am outside, he is scratcch away. I have checked him over and can't see any signs of fleas or ticks. I recently introduced a new ferret, who i checked over before putting them together and he was clean from both aswell. I was just going to get some frontline spray, just in case it was fleas, but having looked online it seems like its prescription online? So i was wanting your opinions on this, as i don't have a clue what to do.
