Welcome to JustAnswer! I am a licensed veterinarian and would be glad to help!
When did this vomiting start?
Is there other illness such as weight loss?
He has done this before but with hairball very seldom he throws up the way he is doing now and it started about three weeks ago since we moved to a new apartment. I don't see any weight loss. His eye lids do look a little pink. When I fed him many times he would just look at the food and turn around and wont eat, then I decided to mix this dry food with another and even though he is eating he still throwing it up.
The chronic vomiting is certainly a concern/
In an older cat - while there can be systemic illness (organ related) - primary intestinal issues (inflammatory bowel for example) would be concerns as well.
For this reason - chronic vomiting issues often warrant some medical testing.
Sometimes I have noticed he also goes under my bed in a corner like a loner and this is not like my cat would ever do that. Maybe hes stomach is just so upset and wants to stay away.
Correct - if he has nausea or intestinal upset - they can certainly act this way.
thank you for your advise
You are very welcome.
