I was wondering how in general animals are treated in Polish zoos and homes?
It depends. Some people indulge their little doggies and there are a lot of animal lovers. Other people are more callous. Remember that Poland is more rural than a lot of European countries and in the countryside people are often less sentimental about pets.
But in cities, people are generally very kind to animals and there is an animal rights movement in Poland.
One thing I've noticed is that people often don't have their pets doctored and this leads to a huge problem with animals that need reforming, puppies dumped at the sanctuary or by the side of the road and kittens drowned. Though not everyone of course is like that.
