Any and Every animal. I'm a vet tech and I have spent my whole career in shelter medicine n helping out rescues. I've worked at one of the biggest SPCA in the country but the down side it had an 80% kill rate, last year they took in 30,000. It was a hard job but I would save what I could. I know have a cat Named Ninja. This owner refused to take him to the vet even tho he had a urinary blockage and had not peed in 2-3 days plus URI. I talked the owner into relinquish him to me. Thank god the vets worked with me and instead of a $1500 plus vet bill, they only charged me a little over $400. Today makes 2 weeks that I've had him. In my eyes if they can be saved and have that fight deep inside them, then I'll be right there by them fighting with them, nursing them back to health. The last 2 weeks, I've had A LOT of sleepless nights but it's well worth it and I'd do it all over again n I will do it again, when another animal needs my help :) this is why I was put on this earth. I've known since I was a Lil girl that I would work with animals n now I'm 30 n I'm doing what I love!
