I was looking at different cat bowls online on the Petsmart website, and I noticed that several of the Whisker City brand bowls are described as "melamine" bowls and manufactured in China. I have two sets of ceramic Whisker City bowls that I use for my cats, so this concerns me. I know that the cats are not actually eating the bowls, but they do put their mouths on the bowls daily and probably inhale whatever chemicals they contain. Could constant exposure to these bowls cause the same health problems that pets suffered from eating the melamine tainted food from China several years ago? Should I get some new bowls, or am I just overreacting?
