I have four loveable barn cats, three of whom are related maine-coons. The only boy, Mickey, hasn't been coming around. When I've seen him, he was skittish and pissy; hissing if I tried petting him, and just very different. I've barely seen him all summer. But the day before yesterday, I saw him, and tried to get him to come to me and remember that he loves a good cuddle. He was still a bit skittish, but I got to love on him for several minutes. He is skin and bones. His coat is rough and dirty, and there's literally nothing to him, but he seems otherwise in good health. When I tried to coax him into the barn, as soon as he saw another cat, he darted away. Maybe they had a tiff and he's the outsider now that got "kicked out?"
Anyway, I've been able to set food out for him, but I was wondering if there was more I could do to get weight on him before winter sets in. My parents have a very thin cat. He always has a full bowl of good food [my mom did a lot of research before settling on Royal Canin] but hardly ate. She started giving him about half a teaspoon of tuna in oil twice a day, and he's gained a fair bit of weight. He's still thin, but it's definitely helped. So I was thinking of trying that? I also heard the kitten food is high in fat, would that be an option? What would you try? Thanks in advance. =]
