So we're considering changing Walli's name to Tank. Not really, but he seriously is every bit of a tank now that he is feeling better. With a healed mouth and the antibiotics fighting off his feline bartonella he eats like a champ! Walli has put on almost 3 lbs in the 3 months we've had him. Sadly, it has come down to us having to hide Sonja's food up high where she can get it and he cannot. He's not the most agile cat and doesn't climb up to the top of the cat tower so her food is safe up there :)
