Many thanks to Ben, Poof242, and Renzo for the thoughtful mails. Max is no longer peeing green, but I will take him to the vet ANYWAY. I rejoice there are concerned and maniacal fert owners who participate... Thank you for thinking of us and, many dooks to you, Sarah, (proud owner of Max, Portia, and Stela, and living in Louisiana, where fuzzbutts are legal and thriving...) [Posted in FML issue 2983]
