It's very possible that your snake is 10 years old. Welcome to the flip side of power feeding, "underfeeding". It's fairly common, too.
Last year I rescued a female that the lady said she'd had since it was a hatchling. It was 7 1/2 feet long and 7yrs old. She has a feeding response like a retic on steroids.
I've got a het labyrinth Burmese Python that I recently got from a fella. It was about 3 1/2 feet long and 3 - 4yrs of age (he couldn't remember for sure).
I've also got some cornsnakes I recently acquired that are said to be about 9yrs old and measuring 3, maybe 3 1/2 feet in length.
Don't try to make up for lost feeding time too fast. I feel a gradual increase in the amount and/or frequency of feeding is the best way to go about it. Don't be surprised if her feeding response intensifies quite a bit. You couldn't pay me enough to step between my rescued female and a rabbit.
If you're not using them already, I suggest a pair of feeding tongs or cheap grabbers to feed with. My rescue is tame, but I don't mess with her a few days before or after feeding. She's got my respect. There's a big difference between her & my 12ft breeder, and the breeder is a good eater, too, just not an aggressive feeder like the rescue.
Good for you for taking in the ol' gal. I tip my hat to you & say, "Thanks!"
Take care!
