I took my 3 month kitten into the vet today... He had been scratching his ears all night and i woke up i saw little brown bits on my sheets where he sleeps... i rang the vet straight away as i was going to book him in for vaccinations anyway, they gave me a appointment straight away. He was checked and the vet said he has ear mites so he gave him some drops (Canaural) and gave him some flea treatment as he said that would help too. How has he caught ear mites? Hes an indoor cat... Can they be harmful to me as he sleeps on my pillow... and most important of all... Do they hurt him?
