Question Extrem slow site navigation / page load

Why is the navigation / page load so extrem slow on catzilla.com? Comparable to an anlog 14.4K or maximum 33.6K Modem...
On all other sites, the pages are loading in normal speed, only here on catzilla not.

I am using Windows XP SP3 with FireFox 24 and have a 50 MBit Cable connection.

We are still working on the site, it's not cached. We will cache it in a few days.
Cheers!
