Ha ha, don't worry about my disapproval. I personally won't remove a cat, but I don't cluck my tongue at those who do - until I have to smell their exhaustI know you are a tree-hugger and you probably disapprove of my irresponsible ways. My house is fitted with solar panels so I think I break even.
It's a personal choice and we all decide what we are and aren't comfortable with.
The bike is looking awesome. Glad you're having fun with it!
