Our previous cat was a very timid house cat.
Yesterday we brought home a five month old kitten.
He has been on every item of furniture, including bookcases. He has been in the kitchen sink. He is on the work surfaces if we take an eye off him. He has been removed from the table 200000000 times.
He has DH wrapped around his paws already. And is being trailed by two over-excited children wherever he goes.
He is sizing up the back door - no way is he going out for a while yet!
