Aw, poor Woogie. What a beautiful kitty though We had another cat, Darby, who went into kidney failure. She had a good 16 years though. :) Thanks for the tip - both cats are already on a grain-free diet (we had another cat, Cali, who had an allergy and really, grain-free is so much better) so I'll talk to the people at the pet shop where I get their food about a low magnesium option.

Ugh, I bet it was. And thank you. :)
