I think everybody cares here and I for one am glad the glider was taken care of and is recuperating. It's because people care that they get so upset when they think an animal isn't being taken care of properly.
Just in the future especially when asking for financial help from strangers (no matter what forum you are using) giving partial details won't likely gain much help. The more details you provide the more help you may receive.
Had you provided this new information to begin with and been more specific it may have made a difference to how some of the people responded (myself included )rather than jumping to conclusions.
Perhaps you can convert your gofundme into donations for veterinary needs that these animals may need in the future. So you already have the funds available if one of them needs vet care in an Emergency like this. Make it an account that can pass from your class to the next so it can keep going.
Secondly maybe discuss putting night security cams in the room the animals are housed in so when no one is there Sat night until Monday you can still keep an eye on them and know they are ok.... security cams aren't that expensive anymore or complicated to set up. Some even have apps so you can use your cell phone to monitor whats going on at night. Just a thought.
