How much harder is it to take care of two kittens then one kitten?

I now have 2 male cats that are litter mates (they are brothers.) Two are not much more work then one and it is good that they have company. You will need a second food bowl, but that's about it. Have them neutered and spayed, if they haven't already been. Of course, u will use more kitty litter and more good quality cat food. Also u will need to take them both to the vet. Definitely worth it!
