If the idea of my dark brown catnip cockroach is too creepy to have in your house (for fear of mistaking it for the real thing!) then how about a colored bug? You’ll keep your cat or cats entertained with one of these felt catnip cockroaches. This cat toy is made from bright green 100% wool felt and is stuffed exclusively with USA-grown organic catnip. The felt body of the cockroach measures 2.5 inches (6.35 cm).
