I just wanted to check a few things about fleas, as not sure. I have been worming flash every month since we got him but the vet said that I didn't need to do flea stuff yet as he was not out and not in contact with other animals, now he is starting to get outside what am I best to do, do I get stuff to prevent fleas and if so what do you recommend? Also how noticable is it if a cat has fleas, have never seen them before so would not know what to look for other than lots of extra scratching! How big are they? Are they easily spotted? I have a flea comb so would that pick them up? questions questions qiestions!
