Dear dear Liz!!!
First, thou shalt NOT beat up thy self!!! None of this is YOUR fault!!! You are NOT " failing miserably! " Things happpen and that is that. Sometimes they can be prevented, other times not. We love our cats and do all we can do for them. Sometimes you can miss a symptom, but in your case, you were right on top of things with Maximus. You took him to the vet right away, and YOU were right, there was something wrong! Perhaps, trying the supplements might be the best way to go for now, Maximus is still so young. It is not easy when these creatures we love so get sick, but we try our best, and you are doing just that!!! Be gentle to yourself!! Sandra
