I have rescued possums before but this is the first full grown opossum I took in. She was skinny unlike the one I have now for 3 years and healthy. I would not normally take in a grown animal like this, but she looks like she hasn't eaten for a while.
I have put all the recommended foods in a cage for her, but she won't eat. I understand that they eat everything so why the hunger strike? Will she starve or eventually eat for self preservation?
Where I live if you can hunt them you can breed them for livestock or what ever. Some places have no regulation unless the species is endangered which this one is not.
