Usher is a maincoon / mix male cat.would be 3.5 years old.Microchipped, desexed but never wore a collar..He has a ginger spot on his left face, large white main, and a white sock on back of left leg.Grey fluffy tail.Has tabby makings, very fluffy. He can e very skittish which is why I can't say he has been stolen as he's very quick cat.BUT I M not leaving the idea that maybe someone has taken him.He went missing on a Sunday night raining heavy.salisbury park area Adelaide diwn sherbrooke road. He went out the back yard at 730pm and I said be a good boy see you later on tonight which is around 1030pm.He never came back inside so I imagined he was out playing. The next morning I noticed his toy sick was moved so he must of came back when I went to bed.830am in the morning and still no usher. I dud oer 250 flyers, located vets, council RSPCA AWL etc.Need him home.Cats don't just vanish.if you know where he could be please contact yvonne 0418850387.thank you
