When we 1st got Gizmo he refused to come out of the pet carrier and was in there till after I went to bed, DH said he emerged not long after and immediately ran for hiding place, we have an indoor balcony so he hid in there for the next two days, he was eating and drinking the food we left out for him but we left him alone to come to us as he was very scared.
By the 3rd day he trusted us more and was coming up to us for cuddles and now he pretty much runs the place!
The vets think he's going to be a large cat and has more growing to do, already weighs half a stone but he's all muscle really, we got him after our other Winston became ill suddenly and turned our he had advanced heart disease, from when we discovered it to him pts was 2 days so that was a shock
