Perhaps your title should not "moderator"..but "bloviator".
... here on a TEMPORARY BASIS. Dogs and cats live for years. What do you expect to happen to that animal when you leave? Just fob it off on whoever is willing to take it? We all have two big vacations a year where we go off to Thailand or home or Bali or whatever and who do you expect to look after your pet? Pets are not disposable. You may think you're doing the world a favor taking home a little hamster from E-Mart but it's even more cruel when you up and leave in a years time and expect someone else to take it or even worse have it put down because you can't take it with you. Unless you're taking your fluffy Persian back...
Back in 2014 I knew a teacher who had basically collected three cats, two hamsters and a fish tank full of creatures.She put a Facebook post up and got rid of the hamsters and the fish tank as they were given away for free. However not the cats as she wanted $50+ per cat.She literally went to the park and released the cats a week before she left Korea! This is why I never had pets in Korea. It’s horrible to just basically throw out your pets
