I think you can name a cat anything including God 
I found the comic quite funny 
I wouldn't worry about pleasing or offending certain groups of people when it comes to creating something on the internet, since no matter what you do, there will always be someone out there that will get pissed off over something
just stick to what you feel is good and not worry about it 
It's free comic on the internet, anyone who get offended by it are free to move on to other things on the internet
