You need to get your girl to a vet for a thorough checkup, including blood chemistry, urinalysis, and thyroid test. It is considered an emergent situation when any feline, esp. a fat feline, doesn't eat for more than 24 hrs. She is at high risk of developing potentially fatal hepatic lipidosis (fatty liver disease) if she doesn't eat.

Please get her to your vet today.

Any sudden changes in your cat, and especially ones that come coupled with rapid weight loss and changes in behavior, are cause for alarm and a vet visit as soon as possible. Do not delay, cats are very small and when things start to go bad, they go bad *very* quickly. The sooner you can bring your cat to a vet the quicker the cat can recover. The cat's recovery will be in jeapardy with every hour/day they are not treated and because cats are so small, they can reach the-point-of-no-return quicker than you think if you decide: "Oh, we'll wait and see how she does..." Please get your kitty to a vet today for an exam and some testing to determine what is going on inside so the vet can determine the best course of treatment.
Best of luck to you and your kitty!

Agreed with the other posters here...sounds like kitty needs an appointment with the vet asap. The fact that is losing weight rapidly is definitely something that needs to be addressed with a medical professional and the purring *could* be due to the fact that she is nervous or not feeling well, since purring can actually be a way for a sick/scared cat to calm itself. Please let us know what the vet says and hope kitty starts feeling better soon.
