Hello, my male bengal "Kobe" (2 yrs old) is losing weight. It has been a gradual process over 3 months. Have had Kobe at 2 different vets during this period and they find nothing wrong. He sleeps more now and has less energy than before. I'm puzzled and would welcome any thoughts.

Hi & welcome to the forum

Has Kobe had all the available blood tests to determine if anything (at all) is wrong?
I'd definitely go back to the vets for another opinion, obviously something is not right.
Is he eating normally? If he's eating normally and losing weight then he needs to get checked out. A 2 year old cat should be full of beans and most certainly have a healthy appetite.
Best of luck x

Have you made any changes to his food? What is his stool like? If it is big and fluffly or otherwise not small and firm he may be having trouble getting sufficient nutrients from the food you are giving him. I have recently discovered that expensive, "high quality" foods aren't always as wonderful as they first appear.
