So I was scratched by an owl, do I need a rabies shot and how long can I wait to get one?

Birds do not carry rabies. But you should get a tetanus shot if you aren't current on your tetanus vaccination. A thorough cleaning of the scratch with soap and water as well as application of a topical antibiotic ointment is important. But I wouldn't worry about rabies since it only occurs in certain types of mammals and birds aren't in that category.

you need to have the scratches professionally cleaned out to prevent a possible nasty infection. That means a trip to the ER or Urgent Care. Ask them about whether Rabies shots are necessary. Do not leave out any details of the incident.

You should really get it looked as soon as possible, but don't wait more than a day or two. Doctor will probably want to put you on an antibiotic as a precaution against any infection that may develop. Infection would be more of a concern than rabies.

If it scratched you with its talons, you'll be fine. That is, you wont have contracted Rabies. But there may have been other pathogens on its talons.

Rabies is transmitted by an exchange of bodily fluids, like saliva, which is why being bit poses the biggest danger.

Also, I don't think rabies affects birds, its mammals that are susceptible to it.

The sooner, the better.

If it did not draw blood - you may not even need shots. But - you need to get it checked out.
