Oh there's nothing to taping... don't worry about it a bit. Lily is 16 weeks old and I just did her ears within the last few days. Just cut 4 squares of masking tape, put one on the front and the back of each ear and that's it! He'll probably scratch at them for a while, but keep him distracted and eventually he'll forget about them. After 2 days Lily's ears went up... one still has a tendency to flop at the tip so I'm still working on it.
Good luck!
