It is the same size as a baby rabbit and is the colour of a wild rabbit with a darker brown stripe down its back, it also has a bobtail. BUT it has tiny ears like a hamster/ guinea pig and doesn't hop but runs like a rat. It feeds on rose petals and clover in the lawn and appears about 2 or 3 times a day. No I haven't imagined it as I have a photo of it which i am happy to share. It's quite cute but is a bit of a mystery
