I assure you I can make the phone balls and the phone case just using fur I brush off my kitties. No pain involved.
I found the accessories quite funny as I rememeber when my own cats were fixed and the vet saw it fit to come outside holding them bloody things to prove she had done the operation. I trust you! I really do! Now get those away from me!!!
Furthermore, the male cats will keep the empty sacs for a while. It looks as if they still have their manhood intact. So you could hold them and their balls separately like that.
