I wasn't sure if you just meant generally or content, so I just did a general look through and commented on what it looked like.
Didn't have a chance to check that all the links were valid, but here are a couple issues I saw as I perused:
1) On the "What to Consider" page, the text was showing up huge and had almost no space between lines...not like the other text at all...
2) On the "Nutrition" page, the word "three" in the first paragraph is partially covered. Also, the header "Pellets" is tabbed in whereas the other headers are not. The header "Treats" is bolded and unlike the other headers.
3) On the "Contact Us" tab, there are "<br>" code on each line
Overall, I would like to see more pictures of what you are talking about in the written content. ie, when you talk about cages, show pics of cages....feed, pics of feed....but definitely more chin pics!
Lastly, on the Home page, it would be nice to say something about the purpose of the webpage, introduction, or what visitors will find there....
