Per the Minnesota Wildlife Rehab Center, if she’s certain the cat never got it:
if it’s a bunny that is larger than a tennis ball, and its ears are upright, it’s old enough to be on its own
Best option is to release it back where she found it and keep an eye on it if she’s worried about the cat again.
Also if she has some greens like arugula, clover, basil, cilantro, or any lettuce except iceberg available those will sit better in the bunny’s tummy than carrots which have too much sugar.
I agree, toll roads charge based on the license plate or scannable toll pass. Did you have a toll pass in your old car? Even if you did, they should be able to see the license plate doesn’t match your account. Also when you called them did you call the number listed in the letter you got from them?
I would try looking up the company’s number online and calling that. Then if it is a legitimate toll charge, doing what dan1101 said should suffice. I definitely wouldn’t send them a bill of sale or other paperwork. If they’re still stubborn about it, a letter from the dealership that you traded/sold that vehicle on (date) might work.
Did you knit it for him? It’s such a great color!
