Sadly I've had to have a few pets put down over the decades .
I learned early on in life that your animals depend on you, it's not fair to let them suffer .
I've had a few mates who 'couldn't bear' to do it so instead they watched their trusting pets suffer needlessly for over a year...
I remember mercy killings in "Soylent Green"

' you gotta tell them ! it's PEOPLE ! ' .
