Being a foster home is one of the best ways to help animals. If you are thinking if you want to adopt an animal, you do not know if it is going to be good, being a foster home is what you should do. Many protectors work exclusively with shelters. Other protectors are nourished by the help of being a foster home, because having a hotel or a hostel is a considerable cost. If you become a foster home, probably the protector you collaborate with will help you with the expenses of veterinarians, guide you, etc.
You dare? Many foster homes end up adopting the animals they host, because they end up wanting so much the animals they have in foster care that they later become final adopters. It is a great way to help, without the commitment of adopting an animal. It is also a way to know the implications of adopting an animal for your family.
