Over the past two weeks we have been trying different ideas on our cats of how to get their breath to smell better.  We have tried 2 different methods one called Greenies for Cats (which comes in four flavors: Salmon, Liver, Chicken, and Fish) and one called Pit’r Pat.  Pit’r Pat comes in a little tin like you would buy mints in at the grocery store and the "mints" are in the shape of fish.  It doesn’t say what flavor they are but Liver is the prevalent ingredient.  When I opened this one up they smelled terrible, but I thought I would give it a try anyways if it would do the job.  I gave one to each of our cats (one which eats everything from human food to dog food, and one who is very particular and will only eat certain brands of food).  Sassy who is so particular sniffed it but would not eat it and Chunk who eats everything gobbled it up and looked for more.  I did not notice an improvement in his breath though.  With Greenies when I gave these to each of our cats they both gobbled them up and come running any time I go near the drawer where I keep them.  I think it helped somewhat with their breath also. These also did not smell nearly as bad as the Pit’r Pat. So out of the two items I would recommend trying greenies for cats if you have a cat who has bad breath.
