Same thing over there is happening in the US. It's horrifying how people think of these pets as just disposable when they get bored. You'd think that people would take the responsibility of owning a pet seriously but no god forbid people take owning a pet seriously.
Currently the shelter in Mass, the guinea pig sanctuary, has well over 300 guinea pigs in a super tiny area, to the point where they can't afford to give them all the space they need, and have been begging other people to foster a bit while they deal with the influx. Like do those kinds of people who just get a pet because they have an impulse realize the harm they cause to the animal by doing it? breaks my heart.
