I would also like to mention that the 'Available' thing can be a little frustrating. You can't click on Available and just go to an available page, you have to go to the 'side' menu of the Available button. The side menu tends to be a little frustrating if you accidently mouse off it trying to get to what you want. Using a laptop with the finger pad or having a shaky hand makes this infinitely more difficult. This wouldn't be a big issue if you could also click on the Available link, then go to another page that lets me pick from the same options as was in the 'side' menu. It's one more click for me, if I choose to go this way, and only one additional page for you but will make all the difference in accessibility.

I would also put where you are located.. Doesn't have to be an exact address, but at least City, 'State', Country. I realize you are overseas ( from me anyways ) but could help out others that might live near you that would be able to save on shipping by picking their animal up rather than paying for the shipping.

Other than that, the site looks great.. I like the colors, design, layout, etc. Very professional looking. Also has a 'modern' feel to it. Great Site !
