I hope Logan gets a clean bill of health. Weight loss can be puzzling. Mac has lost a couple of pounds in his old age (he's in his teens now), and the last time he was at the vets he was fine. If he loses any more weight I will get the money to take him to the vets somehow. Right now he is holding steady, even gaining a bit. He's the most playful and active of my cats so maybe he is okay. Anyway, I'm keeping Logan in my thoughts and prayers.
