The Wild Harvest Stuffed Logz are perfect for small animals who need a little extra help with their chewing. These logs are made of a delicious artificial peanut butter-flavored chewable exterior that is stuffed with sun-cured alfalfa and a diverse blend of seeds. The hard outer texture promotes your small animal’s natural chewing instinct. The logs provide hours of daily stimulation for pet rabbits, guinea pigs, and chinchillas.
