According to the rules of the Stack Exchange network, of which Pets is only a small part, we have to declare an objective scope for our site. We declared our scope to be only pets, and by that we mean "an animal companion that is cared for in a domestic setting and not livestock, wildlife, and pests in and around your home".
We are aware that there's a big grey area around that definition. Pidgeons, rats or rabbits can be kept as pets or they can be wild animals in many rural or urban areas. Tigers, chimpanses or aligators are usually considered wild animals, but some people still keep them as pets. To stay objective in our scope we usually only consider animals as pets when they where born in captivity (bred and sold as pets), lived so long with humans that their behavior matches that of a pet more than that of a wild animal, or if a captured wild individual is docile enoug to be considered a pet (like a bunny, fish or snail).
Ultimately, the reason for narrowing the scope is to keep this site as useful as possible. The variety in pets is already so big that we're unable to answer all questions asked here. The variety in wildlife is even bigger and we wouldn't be able to answer many of them. Answers concerning wildlife are also much more probable to differ depending on the locale of the person asking the question.
In the end, we are a self-regulating community consisting of many individual people who have different oppinions, so some questions in that grey area might stay open while others are closed.
Even if this question was not about a wild animal, closing it would have been appropriate. The help page states:
Emergency medical situations may be accepted on this site provided one or more of these conditions may be met:
- There are potential emergency measures that may need to be taken care of prior to bringing to the vet.
- There is no possible way to seek professional veterinary care at this time.
- The situation is, ultimately, preventable and that it is possible to provide some advice on avoiding the situation in the future.
You stated in your question that there was no vet available, but without knowing the state of the animal (are there fractured bones, internal injuries or other trauma?) we are unable to give you more than the most rudimentary advice like "keep it warm" and "try feeding and/or hydrating it".
