Why does he get to sleep on the bed?
Much like parents can’t play favors with their children, pet owners can’t play favors with their pets. If you have more than one pet, you need to make sure you distribute your love and attention equally between them, otherwise someone might get hurt (and then you’d have to deal with those sad eyes).
Not all cats are friendly and welcoming towards other cats, and they can be very territorial, and so before you bring home another pet, if you already have a cat, it’s better to make sure if he’s the kind of cat that could get along with other pets. While usually, they might leave each other alone, like roommates who want nothing to do with each other, cats could also get jealous of one another.
