My 4 1/2 year old Bengal used to have a great appetite. Now she only licks her wet food dry with maybe a couple bites. Very seldom does she eat any dry food anymore. I've tried all types of wet food and even pureed food which she will lick, but not large amounts.
She did get sick couple weeks ago (with a fever of 105 °F / 40.6 °C), but she started this behavior shortly before that . She is back to her normal personality but still very limited eating and losing weight slowly. Altogether, this has been about 2 months now.
