Many people do not realize what all it takes to become a rescuer or what a rescuer has to go through. It involves long hours, frustration, no pay but many rewards from the animals you save. It is very costly to rescue. You need to purchase supplies you will need to properly provide for the animals you are going to rescue not to mention the stack of veterinarian bills you are going to have. Many of the animals you are going to rescue have either never been to a vet or are not healthy and need immediate medical attention.
Some rescues appear healthy only to find a serious medical problem during a vet check.
The bird lived less than a year before it's poor little system couldn't take it anymore from the years of untreated illnesses by its former owner. I have had puppy rescues die in my arms the next day after saving them, only to find they had distemper. I would cradle them in my arms trying to will them to live, telling them how much I loved them and praying to God to spare their lives as they were dying. This became too much for me to deal with so I decided many years ago to stop taking in abandoned puppies and rescue abandoned pregnant dogs. The puppies are born in my house free of parvo and distemper.
