Commas are necessary. It is the current trend to eliminate as many as possible but please be careful. Your pets will appreciate it.
I am a purist when it comes to grammar. Yes, I adjust my style to reflect my individual clients but… Commas have been getting a bad rap lately. Less is more, they say. Keep the text fluent, they say. However, we need to remember that commas are not only used for pauses in reading. They affect the meaning of the text. Remember moderation in all things!
