Amusing cartoons
Format: Paperback
So two cats create a mechanical dog suit to fight crime and, in the end, save the planet. Mostly fun times, although there are some stretches of credulity in the overall story. Generally fun, however.

Two earth cats Vs. Three aliens!
Format: Kindle
Crazy! I didn't expect that the super hero dog was actually two cats! It was a fun surprise to find that out and learn their history! I would recommend this book for readers who like aliens,cats,dogs,mystery...(squirrels,explosions,and even blobs.)

Great for reluctant readers
Format: Paperback
My 5th grade reluctant reader said it was very funny, and gave it 5 stars. It would be great for fans of Dogman, as that is his other favorite series.

8 yo’s favorite books!
Format: Paperback
My 8 yo son is reading his for the 6th or 7th time. The only my thing my son didn’t like about this book is that there isn’t a sequel.
He says “I wish I could put a billion stars”

Definitely a Must-Have
Scent: Sandalwood
This beard kit is legit. The sandalwood scent is clean and manly without being overpowering, which makes it great for everyday wear. The oils and balms actually soften coarse beard hair, reduce itch, and leave the beard looking healthier and more manageable. Packaging feels premium and the pump bottles are easy to use — no mess, no waste. I’ve tried a lot of beard kits over the years, and this one hits the sweet spot for quality, scent, and value. Highly recommend if you want a well-groomed beard that doesn’t smell like “baby powder mixed with perfume.”
If you have facial hair, you’ll notice a difference after the first use. Worth every penny.
