You're welcome @whatisnew! I think you are right on the hemlock affecting him. I can't even imagine living next to that. Friendly is older too and my husband thinks it's age related. She is only 12 years old maybe but she was an outside cat and has always had tummy issues. Be careful if he licks plastic bags. Tiger does that but I try to stop him when I see him doing it. That made a friends cat very sick. I hope and pray he continues to improve! xoxo
