In the arena, the page numbers at the bottom do not register at all for me. I never get past the first page. Which sucks since most of the time all of the pets on the first page are grade 2 or 3 and I'm trying to level a no grade. Kind of frustrating, I thought the pages just didn't work, but then I watched a friend work them just fine. Just my account?

Try hard refreshing (= pressing Shift+ F5). I had this problem in the beginning too and this made it work for me. You can also try clearing your browser cache, someone else mentioned that did the trick for them. 

That worked!! Thank you so much! So simple as to refresh a couple of times xD Wow. Thanks ^^
