Fantasy to be a Pet

if you've read my profile you'll see that I love to wear a collar and lead. I often fantasise about taking that one step further and playing as a pet. I would love to meet up with someone that has a cage and other pet equipment such as food/water bowls. Would love to be put in a cage for a while to wait for Master to let me out and play. Take me for a walk on all fours, let me sit at his feet. Putting my face in his crotch and maybe sucking him off whenever he wants. Of course I love to be on all fours and fucked either by Master or another pet.
