Raisins for rabbits

[BlackSpruceRabbitry7]

I have read you can give rabbits raisins for a treat. Some people said one raisin a day, and some others said 1-2 a week. What is right?
What kind of raisins would be best for rabbits: Sultana, Thompson Seedless, or Golden Seedless?

There is no real "right". Just use sparingly.

When I'm giving a rabbit shots, or changing a bandage, or something, I'll give up to 5 raisins at a time, every day, for a week.

That might cause diarrhea in some rabbits, though.
