Oh, poor Brynja -- and poor YOU! My sister's cat (Seymour) suffered from a similar problem. That boy could make your eyes water! My sister noticed that it was especially bad after any kind of fish. When she stopped feeding him seafood, it almost stopped completely. Seymour's vet also suggested trying CurTail. http://www.akpharma.com/curtail/ A few drops of these natural enzymes on Seymour's crunchies really did help until she figured our that seafood was the problem.

Good luck with your little "stinker".
