@RareBreed Your babies are adorable! I didn't see where anyone had mentioned this yet other than about a Cat Tree, but get them a good solid scratching post asap. Yes, a sturdy Cat Tree is perfect for this. They absolutely must learn to use a scratching post when young if they are going to be indoors because they will shred everything in the house. It is amazing the destruction a cat can do sharpening it's claws! Having had cats before you probably already know this, but thought it was worth a mention. Happy Kittening!
