Hana--I am so glad that I am not alone in this. I know it is a terrible thing but I have to laugh at the way you described your situation. I can totally see Buster and Rock at opposite ends of the same couch going to town. They sound alot alike. Rock will eat anything...bitter, sweet, hot or cold. He actually eats onions and tomatos if he can get my hubby to give it to him. Anyway as you hear of solutions let me know and I will do the same. MeganMK--Would not the vinegar smell? It might work because it is a foul taste but I worry about an odor.
