So, I'm nervous. They're treating him as a heart patient, but still I'm nervous. What would I do if something awful happened to my little guy.. i couldn't forgive myself. I feel bad also that I'm not spending time with him all day. I feel bad that he's at the vet all day tomorrow, he's afraid of some of the cat sthere (they have 2 main coons.. one stood on his carrier.. it really freaked him out. ) I'm really worried...
