What a fun topic! I love hearing about everyone's pets!
We live with Pico, my English Cocker Service Dog; Jack, a huge old grey Flemish Giant rabbit; and Mike, my approximately 20# cat. They are all about the same size. Pico and Mike are both rescues. Pico lives whereever I am, Jack has run of the back yard and the back porch (where we hang out daily in all weather), and Mike goes in and out. They all get along amazingly well. When we first got Mike, he tried stalking Jack and Jack turned around and stalked him. Mike and Jack now share the litterbox on the porch - though they both also use the yard. All three of them share the outdoor water bowl. We also had a chincilla for a week this fall - it got lost from the neighbors a few blocks away - luckily we found her family.

. Jack is now an old recluse and doesn't have a web page.
As a child, I had lots of lizards and a water garter snake. I'd love to have a snake again, but I seem to always live with people who don't like snakes. Plus, I'd really like a boa and having rabbits and a boa isn't necessarily a good mix.
