I have a few cat chewed childhood ponies. Poor Whirly!
Wall mounted shelves out of reach or doors. If you have a collection room, simply shut the door. If not, shelves with glass doors (or add doors to existing shelves).
Congrates on the new kitty! Those are some wild eyes in the picture but your cat should settle in eventually and hopefully ignore your collection once it's nothing new to explore.
Wall mounted shelves, if your cat isn't a climber / jumper, are really good. Otherwise bookshelves with doors on them if you don't have a room you can shut off from your cat to keep them in.
Good luck! I hope your new kitty settles in quickly and has no interest in your ponies.
