Doing rescues is an arduous process most of the time.

Even if you get them for free, you take them to the vet, pay the vet bill, take care of any illnesses you encounter, and feed them. Then, to get someone to adopt the animal with an adoption fee which usually does not compensate for the money you have put in is difficult as well.

I have done this on several occasions, but not to actually adopt out. I usually keep them.

It is worth it to get them healthy, but to adopt out, most of the time you will be taking a loss.. Just a thought. As long as you can afford it, do it.
