We have this bright orange bag that we got when we bought some cookware and it is a cat magnet! Without fail, every time this bag is left out the cats are laying on it or touching it in some way. In the case of the photo below the bag was full and laying on it wasn’t an option so Charlie stood next to it and pulled one side down so he could at least get his front paws onto the bag.
I conclude therefore that cats either like this bright orange colour, or, they have been paid by Le Creuset to advertise their high class cast-iron French cookware.
When I say “wasn’t an option” up there I think “wasn’t something he was in the mood for” is probably closer to the truth. When not being mesmerised by orange bags our cats are seeking out uncomfortable things to lay on. For example, why lay on the sofa or a nice flat floor when you can lay on the laptop charger cables or the tv remotes or a pile of books?
