Hi, My cat recently has lab work done, in which the results of the draw showed high eosinphil levels. He's eaten very poorly over the past few days, although his appetite has certainly improved with a use of appetite stimulant. Regularly, I allow him outside, but only for short amounts of time. What can my cat's lab results indicate? 5 y/o brown male tabby neuter- w/o signif past medical hx

Hello and thanks for your post!
Unfortunately there are a lot of medical problems that may cause eosinophilia.
Eosinophils higher than normal can indicate an external or internal parasitic infection, allergies, inflammatory bowel disease, or certain types of cancers or tumors.
You may want to see if an abdominal ultrasound or x-ray might be done to check his internal organs and help rule out cancer or a tumor.
I hope this helps and best of luck to you and Hemingway!
