Metacam?

So houdini went to the vet yesterday. He had stopped eating his pellets. He was still eating plenty of hay and pooing fine, fully active and alert as well. I had also noticed some blood on one of the ledges as well. I saw no abrasions or cuts anywhere on his body or his paws and feet. Possibly from his urine. His father had just got treated for a bladder infection recently as well.



I got the antibiotic for his for the possible infection. But they also gave me a bottle of Metacam Oral susp/ melooxicam (so says the label) .2 ml once a day.



I had just heard that metacam can actually suppress appetite. Is this true? If so is it a good idea to use this now considering he stopped eating pellets?
