We purchaed some plastic ornaments, for outdoor use, many years ago at Home Depot. They are clear with holly, poinsettia, etc. inside. Have had them for years and if they get knocked off or tumbled around it is no problem. They are good for toddlers who like to touch and I'd think that kitties would do the no harm as well. Also have some wood ones that I got at Michael's and painted, they are cute and pretty indestructible. Hope this helps.
