My wife uses those soft claws things where you glue them to kitty's claws, they stay on for a couple of weeks and keep her from scratching the furniture up. as for the cat atleast you won't have to worry about mice eating your planes up. I'd much rather see damage that i can fix than some wires in a model be fraid that i don't know about and loose the whole model. just a positive lookout i guess.,
however the soft claws work pretty well for our cat and you don't have to worry about declawing the cat too. they make it a lot easier on your hands when you play with her, unless she looses a cover then the ole switch blade gets me then.
anyway good look with trouble sounds like he's entertaining at the very least.
