Turns out that all 5 newts, which were rescued, came from a really bad situation where the owner was extremely neglectful. The lady from the rescue who I initially contacted said she didn't have the resources to keep them and they are in really bad shape, so she ended up giving them away to another rescue who does have the means to care for them. The woman at the other rescue says that the newts are "sick" or have a "disease" but wasn't clear on what it is. I plan on calling to find out what's up and to see if they'll still be available to take in. Apparently, she wants to care for them and nurse them back to good health beforehand. My thing is, why not just take them to a vet? Maybe there's not one within the vicinity. I wonder if most vets are willing help out animal rescues for free too...
