Is this niche specific enough?

I have posted in a previous thread about finding the right niche and sports and pets I have a high passion for. I decided to start an online store selling pet products but instead of creating a general store and selling hundreds of common pet products I thought I would dig deeper.

I came to an idea to sell sports products for pets. I have a lot of experience and knowledge in the field so I figure I could come up with a strategy to market pet sports apparel. Going to local games and advertising, writing post-game articles and somehow tie the pets in the article, and also have a weekly contest of the coolest pet who is decked out in their favorite teams gear!

Now I have a couple name ideas that I wanted to use but I couldn't really come down to a final decision. I know its all about following your heart and what sounds best to me but if you all were guests on my store and you seen the name, what would stick in your mind more? (Now mods/admins who read this, I am not here to spam I am not posting any links, I just want to hear some opinions on this.)

I have PetMerch as one name and Petletes as the other. PetMerch I was using as a general pets store. Not too sure if it sounds sporty or a place that would sell nothing but sports apparel. Now Petletes, is the same word and replacing the word "Athletes". Athletes who are known as humans, Petletes are simply pets who are sports crazy too

I have some good marketing strategies. I have a good follow base on Instagram, Facebook etc and I have $ to advertise. But what sounds best ?

Is the sports niche deep enough?? Instead of focusing on ONE particular team because then I would be really limited.

Thank you guys and gals!
