What are Solid All Natural Willow Chew Balls? Solid All Natural Willow Chew Balls are 100% willow wood harvested from QiLiu Willow trees, close relatives of Purple Willows. They hold a naturally sweet taste with nothing else added—no dyes, sprays, or fillers. Unlike a straight chew stick, the ball shape gives rabbits, guinea pigs, chinchillas, and pocket pets like rats, mice, hamsters, gerbils, and degus something to push, roll, and chase while they chew. Are willow chew balls safe, and how sturdy are they? Yes. Willow Chew Balls are single-ingredient wood with no dyes, sprays, or added chemicals, so they're safe alongside our Willow Chew Sticks. Rabbit and rodent teeth grow continuously, and chewing wood helps wear them down naturally. Willow is a naturally soft, sweet wood, so a ball is meant to wear down and even crack with regular chewing rather than stay rock-solid forever—that's what makes it chewable in the first place. Supervise the first few sessions with a new pet, and swap in a fresh ball once one gets small, cracked, or fully chewed through. Which size should I choose? Small (4 Pack) — 4-inch-diameter balls, a good fit for guinea pigs, smaller rabbits, and pocket pets. The extra balls in the pack mean you always have a backup ready. Medium (2 Pack) — 6-inch-diameter balls, better sized for larger rabbits or pets who like a bigger ball to push and chew. What are the key benefits? Single ingredient — 100% solid willow wood, naturally sweet, with no dyes, sprays, or additives. Rolling enrichment — the ball shape adds active, foraging-style play, not just standing-still chewing. Supports dental health — chewing wears down constantly growing incisors and molars naturally. Eases boredom and stress — gives pets a natural outlet that curbs anxiety and destructive chewing elsewhere. Multi-species safe — good for rabbits, guinea pigs, chinchillas, rats, mice, hamsters, gerbils, and degus. How many chew balls should I give my pet? Keep a chew ball available at all times rather than offering one only occasionally—it gives your pet a safe outlet whenever the urge to chew hits. Most pets wear a ball down or crack it open over one to a few weeks, depending on size and how hard they chew. Swap in a fresh ball once the current one gets small, cracked, or fully chewed through, and supervise the first few chewing sessions with a new pet. Grass hay like Ultra Premium Soft Timothy Hay should still make up most of your pet's daily diet—chew balls are a supplement, not a hay replacement. How do I store and use willow chew balls? Store balls in a cool, dry place with good airflow. Damp storage can lead to mold, so avoid sealing them in plastic long-term—if a ball ever smells musty or feels damp, discard it and open a fresh one. Roll a ball across the floor or tuck it into a hay pile to turn chewing into a chase-and-forage game. Rotating willow chew balls with other shapes, like willow chew sticks, keeps chewing interesting and encourages natural foraging behavior. What if my chew ball arrives damaged or falls apart quickly? Willow is a natural, somewhat brittle wood, so a ball can occasionally arrive cracked or wear out faster than expected, especially with a heavy chewer. If that happens well before your pet has had a chance to enjoy it, contact our customer service team with your order number and we'll make it right.
