Is it possible to have a cat and keep my home nice?

yes it is you can have the cat or kitten declaw but make sure it is old enough for that and so he does spray on the carpet you can have it spade or nutured and get a cat comb or one of those lint rollers to pick up fur it sheds and when kitty litter training make sure you hold him in the litter box so it clicks that the litter box is to go to the bathroom
