Snoodle-

You mention she has had kittens but did not say it she was now spayed. If she is not that alone could be the cause of her malnourished look. At any rate, being deaf or blind should not affect her appetite, so she may need a visit to the vet.

My brother had a cat who, like many cats, developed kidney disease as she got older. What they didn't realize was that the disease had caused her to go slowly blind. She adapted so well, though, that they never knew it until she was totally blind and bumped into a chair that had been rearranged. She had been going outside and everything, and no one knew she was totally blind! She lived a couple more years like that before finally going to the rainbow bridge!
