Cats without a home
All cats should have a loving home. It is uncomprehensible that cats still are used as toys during summertime and then abandoned.
There are many who help cats, both by taking care of them, giving them food and vaccinations and then trying to place them with caring people.
When you help by giving money, please make certain you give them to serious people, and that they use it in a way you appreciate. There are some scumrats in every kind of help organisations.
