There's a local pet shop in my neighborhood, and it is overall an okay store... for most animals. The hamsters and rabbits have fine cages, but the rats and mice are housed in a way that looks pretty bad. The cages are about the size of a 50 gallon aquarium, but there must be almost 30 rats in it... all jammed together. The cage looks clean enough though. The mouse cage is the same size but with more like 45 mice. And all them are PEWS (I don't if that's the right term for mice) so I kind of wonder where they came from. I just want to check if this is animal abuse, and if so, what can I do?
