I used a mini Duna for awhile and once I'd licked the little suckers they rarely came off the plastic.
I agree with SS about getting a bigger cage,I did have all my hams in cages that weren't big enough ( I found out what sizes they should have been in from joining this forum and bought them all bigger cages,wish I'd known earlier.Your ham will definately benefit and appreciate a larger cage,the difference in all mine once I'd upgraded them was brill)
