My Pets

My dog, Klinky was about to turn 18 years old, but she got so old that she was blind. So we brought Klinky to the vet so he (he is the vet)  could put her down (put her down means to kill a dog because they are to old).  So she died.   
:( 

But moving on i have two cats that are three or two years old (but i wish they were sill Little). My cats names are Otto, (Otto's a tabby cat) and Rocco (Rocco's a orange tabby cat). And there all nice and healthy. 

My cats liked to 'play' with my dog but because my dog died I wonder if they know shes gone?
