Here's why:
* Raccoons are wild animals: They carry diseases that can be harmful to humans.
* Lumps can indicate various issues: It could be an infection, an injury, a tumor, or a parasite. Only a qualified professional can properly diagnose the issue.
* Raccoons can be unpredictable: Trying to handle a sick or injured raccoon yourself can be dangerous.
Here's what to do:
1. Keep your distance: Do not approach the raccoon.
2. Contact a wildlife rehabilitator: They are experienced in handling and treating wildlife, including raccoons.
3. Contact a veterinarian: If you are unable to reach a wildlife rehabilitator, a veterinarian can also offer advice or treat the raccoon.
Please remember: Your raccoon's safety and health depend on professional help.
