I have partys for both my cats and dogs! Special dinner, treats, catnip(cats), chew bones(dogs) and of course playtime and they even get Happy Birthday sung to them along with a cake or cupcakes and candles! I know my Missys birthday 2/27 and Sassys is a close guess from the vet when I found her on the street, 8/5. Sassy is 5 1/2 and Missy is 5, just had a birthday!
