You're very welcome. I love doing rescues. My parents started me into it very early and my children are involved in it now. My youngest daughter, Sarah is 11 and she has been doing it since she was 6.
I hope that eventually you reach your goal of helping animals!
As far as the cat goes you tried to save, Sarah, found a dog. Seriously emaciated and almost totally hairless. The vet gave her about a week or so without our intervention. She's been with us and on meds and finally fed regularly for a few weeks. She's got a brother. We can't save him. He won't come to us and we can't get close enough to rope him. He will more than likely die and his owner refuses to get him medical treatment. Sarah "found" Lola, and we know who her owner was. We got the SPCA involved, but due to the way laws are written here, their hands are tied to get the other dog or press charges for Lola's neglect. However, they granted us permanent custody and told us under no circumstances to return her to the guy who owned her before. (Duh, like that was going to happen)...
Animal rescue is victory and defeat... Life and death... Sometimes the ones you think are going to be fine die in your arms while you cry and no one can fix it. Sometimes the ones with death sentences are like Sabbath and Lola and you get loads more years with them.
It's an emotionally, physically and financially difficult life, but if you choose it and you can make it work, the pay off is incredible. <3
