Yes, many rabbits do enjoy celery, although if you are planning on giving them this make sure you cut it into pieces about one inch (2 cm) long. There is some talk that the strings can cause choking in rabbits, so cutting them into short pieces will avoid this concern. Also, only the dark-coloured celery leaves are very healthy for rabbits; the light-coloured leaves and the stalk itself are only good as an occasional treat -- they're low in nutrients and can lead to diarrhea. See the related question below for more info about the rabbit diet.
You should be cautious when giving rabbits celery. Celery is very stringy and can interfere with digestion. It is recommended that you cut up the celery into very small pieces before giving it to your rabbit.

No, rabbits do not have the ability to purr.
Some rabbits have a taste for celery and some don't. You can feed your rabbit celery but if your rabbit doesn't like it, you shouldn't force the rabbit to eat it-- even if its healthy. Celery is a good treat for rabbits. It should be handled as a treat though. A small piece every couple of days is enough.
