RIVERDALE If you've been thinking about adopting a pet, mark your calendar. Sunday October 9, between 11 a.m. and 4 p.m., at Mike's Feed Farm store on the Hamburg Turnpike in Riverdale will hold a pet adoption day. Store manager Kelly Delia and assistant store manager Kim Stortz, along with owner Mike Goldsmith and Dr. George Cattiny, Jr. of the Pompton Lakes Animal Hospital are working on the final stages of planning the event which will include some animals that are rather non-traditional pets. There will be numerous representatives of area shelters and rescue units including, but not limited to Haskell's Furry Little Rascals, Friends of Wayne Animals, Gentle Giants of Wayne, the Rottie Connection and the Safe Haven Rabbit Rescue. Adoptable animals may be as varied as hamsters and chinchillas to Great Danes and St. Bernard's. Participating shelters and rescue groups will bring animals ready for immediate adoptions, and the Passaic County Spay and Neuter Coalition mobile unit will be on-site too. Other exhibitors scheduled to participate include a bear group, but they will be selling bear-proof garbage cans, and not offering cubs for adoption. There will be parking available next door at Slater's Mill, and volunteers from the Riverdale Police Department will handle traffic control. Dog and cat food manufacturers will offer free samples, so you'll be able to bring home some new treats for Rover's discerning palette. There will be coupons, gift certificates and other giveaways, and lots of information and advice on the care and feeding of a variety of types of pets. Mike's Feed Farm has been in business for about 20 years, offering natural, rather than supermarket-type dog and cat foods, as well as other pet foods. In most of the products sold the main ingredient is natural (or organic), whether is birdseed or "raw" dog food. (Raw dog food is a frozen food product that has been available for only the past two or three years, according to Kim.) In addition to the store in Riverdale, Mike's Feed Farm is also located in Totowa NJ. According to Mike, "all employees are working very hard to make this event a big success."
