When Chloe was ill for all those years with her AIHA, I felt pretty much as you did. All the drugs and the fear of what they could do to her little body. Feeling sick with expectation at every blood test. Like Mac, she sailed through it all, never stopped wagging that beautiful tail and took her treatment like a little heroine. Apart from being overweight you never knew how sick she was. I know how you want to do something more, make it all stop, lighten the burden of being sick for them but you just can't. To be sat there feeling so sorry for Mac, worrying about him and taking pleasure in him eating his tea just shows what a caring parent you are to this special baby. I hope he improves at the next test and gives those daffs a good trampling.
