Brrr! Really cold out there! Artie might not be at his best, but consider his conditions, he might be not too hungry sometimes. Have you tried cooking him something totally new? Maybe a new recipe, made from the heart of his mom, would entice him more. Hopefully the NVet is back to office now, holidays are over (even over here!) and everything should fully work! Come on Artie, be good, it's Christmas, give your Mom a wonderful present, I know you have it hidden somewhere and are waiting the right moment to give it to her. Well, that moment is NOW!
