Way to common over here. People rent houses in the countryside during the summer, and because they are spineless, stupid, ignorant aholes, they cave in to the whining of their kids and get a little kitten. Oh how fun, look at it, ooops, we're going back now, and we can't bring the kitten with us, so leave it, he/she will be alrigth, there's...mice, yeah, mice that it can catch and eat. It'll be OK.
Kitten is promptly abandoned, probably asking itself "why did they leave me
?", and eventually they die either of cold or starvation or are eaten by some predator.
I don't have any pets, but my parents have, and well, they are family. Hairy, sometimes smelly and odd family, but still family. If I had pets, and had to leave, pets go with me.
