Under normal circumstances, Siamese cats do not have much body odor. If your Siamese cat always smells bad, you need to pay attention. The first possibility is that the owner has not bathed the cat for a long time; the second possibility is that the cat’s diet contains too much meat, resulting in fishy feces; the third possibility is that Cats suffer from dental calculus, ear mites and other diseases, which cause bad breath and ear odor. In this case, you can usually see obvious black dirt on the cat's ears and yellow food residue on the teeth. At this time, the owner needs to find a solution to the problem.
