Demand Pets at Home to stop cruelity

I saw 3 hamsters in one very small glass box in their shop
1/ This is very cruely the hamsters did not have ANY space
2/ Having only very limited space increases aggression and they are more at risk of harming each other
3/ People get their advice and guidance from pet shops - people will believe that it is ok to keep them in very small cages
4/ For all pet shops to stop selling TOO SMALL Cages NOW
