I don’t see a problem in tagging animals for practical purposes such as identification. I do a problem with it when it is just done for ‘decorative’ purposes. Cropping tails and ears is also a no-no for me. Spaying and neutering, on the other hand are usually positive things.
I can’t understand the earrings on babies thing. Parents don’t expect babies to pull them off and swallow them?
Decorative? Entire breeding programs exist for the sole purpose of making a more “decorative” pet...
