Design a simple and fun logo for Pet Thunder

Pet Thunder

Pet Thunder's mission is to make every pet happier and every pet parent's life easier. To that end, we sell pet products that pets enjoy, and save a meaningful amount of time or effort for pet owners.

We currently sell mostly in the US and some into Europe, but plan to continue to expand. Our customers are typically older than average, have a high disposable income, high education level, and are more likely to own their home. They are frequently located in suburban households, and skew slightly female.

The logo needs to evoke "Thunder". Our name is made up of two words, Pet Thunder, and "Pet" is not the memorable part. There are a whole bunch of pet logos out there, and they're incredibly difficult to remember because there is nothing unique about them. We have a cool and unique name by incorporating the word Thunder, and so I think it is important that any logo submissions strongly evoke thunder in them.

It is important to convey that the Pet Thunder brand is fun, but not at the expense of appearing to be low quality or cheap.

Two things:
1) Though it shouldn't be considered part of the logo, we need to include the registered trademark symbol, as the name Pet Thunder is a registered trademark. (And we do eventually hope to trademark our new logo as well.)
2) I have attached our current logo for reference purposes. WE ARE NOT TIED TO THIS LOGO. It was a cheap and fast logo chosen primarily to bring us to market more quickly. However, do not feel beholden to its design if you do not want to be constrained.
