Yep, that's pretty much my opinion too. Body art on a person is their choice, on their cat, well.....again, their choice unfortunately!
I'm less disturbed by the giraffe design and moon design (and possibly even the halloween design) purely because the dyes haven't changed their fur colour as far as I can tell.
I wish people would just see the beauty in the animals that surround them and realise how honoured they are, rather than trying to beautify things all the time.
