Hi Thomas,

Cutting it out with scissors seems the safest option.  Use blunt-nosed
nurses' scissors, though, to limit accidental damage.  Even this will
require a certain amount of feline cooperation/patience.  If possible, get
someone to help you hold kitty while you snip.

Other, more usual ways of removing candle wax (on textiles, for example)
require solvents or re-heating with a household iron.  These are obviously
not appropriate for cleaning kitty.

Candles and kitties are mutually exclusive.  Both should be supervised.

Good luck.
