If your pet needs more than the standard Purina mix, then you might want to consult a nutritionist. EarthWise Pet Nutrition Center and Wellness Spa is open at 22010 Westheimer Parkway, Katy, said Nick Scherf, store manager and certified pet food nutritionist. The store will host a grand opening celebration March 2 with raffle prizes, activities, and discounts on products and self-wash pet services. The brand offers natural and alternative pet food, pet toys and pet-grooming services. If you aren't familiar with pet nutrition, take Fido for a bath and learn all about it!
