In our neighbour's garden, their cat Diego was happily sitting in the top of their pizza oven (never used). Unfortunately for him his tail was hanging out, moving around and noticed by Silver who is still very playful and tries to get a hold of anything that moves, like Diego's tail ;-)
Silver then said "peekaboo" (in cat language) to Diego from the front which startled him a bit.
Diego was out of his little hiding place pretty quick! ;-)
Silver has no fear it seems. Diego is bigger and stronger and more experienced outdoors. But he accepts Silver completely and even lets Silver into his house when the backdoor is open.
