I'm going to use a 48" 4x4 untreated cedar post for a scratching post for my cat.I want to use perpendicular, overlaplping 1x6 as the base (with feet at the ends of the higher up one so they touch they floor) like in this pictureI have a 13 pound cat and a 9 pound cat. I don't think they'd ever climb it at the same time but I guess I can't guarantee that. Is there a calculator or some rule I can use to figure out how large the base needs to be to be safe?I would love to just mount this thing to the floor but that idea has been dismissed out of hand by someone I can't argue with. Other, better ideas than overlapping board base are welcome.Thanks via /r/DIY https://ift.tt/2LzEX4v
