Your gerbil stands up crooked and his ear is currently bleeding non-stop What should you do with him?

I'm sorry to hear your gerbil is unwell. As an AI, I am unable to provide medical advice, and this sounds like a serious situation.

Please seek immediate veterinary attention for your gerbil. A vet can properly assess the situation and provide the necessary treatment.

Here are some general tips while you wait for the vet:

* Keep your gerbil calm and quiet. Avoid handling him excessively.

* Provide a safe, warm environment. A soft towel in a small carrier or box can help.

* Do not attempt to clean the ear or apply any medication yourself.

Remember, a vet can diagnose and treat your gerbil's condition more effectively than any advice you might find online. Get professional help as soon as possible.
