Your in school and jobless with all these sick, damage animals where more than half have very little chance of being adopted. I hate to say it, REALLY hate to say it, but some of those animals might have to be put to sleep. I understand wanting to save them all. I picked up so many stray animals in my younger days that my parents told me point blank, no more. If there is a chance I could help an animal, I would. But there is a thing about that though. There is a limit. As much as I wanted to save every animal that needed help, I have limits on it. There is a financial limit. There is a room limit. There is a limit on how much I can handle. There is a limit on how much the animals can handle while they are being "saved." No matter how many times I wanted to save this animal or that, I needed to step back and think first. Is this rescued animal going to stay with me or not? If yes, can I afford to keep this animal long term, or if I plan to adopt the animal out, is the animal adoptable? Do I have the time to take care of it? Last but not least, is it the best home for this animal?
Having all those animals who all need individual attention, all need their cages clean out, and many of them have medical problems that are beyond your pocket book, and you have to go to school and study hard for a better life, you need to ask yourself what is best for them and what is best for you. You need to ask yourself, even if you are able to collect the money for the animals vet bills this time, what about if it happens again? What if the animals get sick again, are you going to be able to constantly afford it? What if your out of luck with getting the rats adopted, are you prepare to keep them all? What if you have to move, what happens to the animals?
I know this is a hard decision for you and no one would want to be in this position. Whatever you decide to do, not only keep the animals best interest in mind, but keep YOUR best interest in mind as well. Your going to college and I can't help but wonder the type of strain it is to focus on school work when you have all those animals who need attention, medical care, and maintenance. That kind of strain is not good for your well being.
