underweight Calico

Question
My almost 6 yr old Calico, Lily, seems to be very underweight. she's an indoor cat, eats regularly, but often vomits it right back up. we make jokes about her being bulimic or something, but I'm getting concerned about Lillian. Any thoughts?

Answer
Brian,

You need to find out why she is having trouble keeping her food down.  Have you changed her feed?  If not, you might check with a veterinarian to see if something is going on with her.

It is normal for cats to have some throwing up, but not every time they eat.  There could be so many possible causes of this problem, you need a veterinarian to help diagnose what is happening with Lillian.

You may have to end up changing her food to something her stomach can tolerate more easily.

Best regards... Norm.
