I got them on her very easily with NYC's burrito towel suggestion. Took me longer to figure out how to open the glue.
Only one has come off and I'm cool with that. I realized that this will probably interfere with her climbing our 3 tier cat trees (she's a tree cat). This will probably be the only thing that would dissuade us from using them. Hopefully I can figure out which claws are her "action claws" and just cap those in the future.
