I came across this fantastic Joomla template by Template Monster a few days ago and believe you would like it as well especially if you have a niche pet related site.

Compatibility: FireFox, Internet Explorer & Chrome tested.
Version: 1.5 (Joomla).
Price: $55

Iconic Design
The entire template design is very visual and it captures the attention of the visitors very well. The header stands out from the template, with nicely decorated side menus, both at the left and right. There is also a top navigation bar for you to highlight important internal links to your site.

Great for niche pet site
In my opinion, this template is highly effective if you are targeting a certain pet type and offers membership content. For example, members can login and subscribe to certain modules to learn more about the pet that you are targeting.

I would also advise if you were to use this template, try using a lot of visuals on the front page to capture the attention and get the visitors to sign up with you for freebies or access to certain parts of your site.
