The 2354 Pk4 Small Sola Atta Ball from Bonka Bird Toys are first-rate bird foot toys that pets absolutely love! This bird toy pack includes (4) small sola atta balls. Each sola ball is made from the stem of the Sola plant. This plant's botanical name is Aeschynomene Aspera and makes for the ideal bird (and other pets too!) foot and chew toy. The sola material is soft, spongy, and super easy for pets to bite with their beak and grab with their feet. The sola stems have been arranged in an eye-catching ball formation that you and your pet will adore. The balls can be easily broken up to make different shapes or to provide extra chewing and foraging material. The sola material also weighs very little, allowing your pet to pick the balls up, toss them around, and manipulate them as they see fit. The sola balls are great for other small pets providing a safe, natural chew material. The sola balls can even be used for traditional art and craft projects with their charming shape and neat-looking surfaces; the 2354 Pk4 Small Sola Atta balls are 100% bird safe, and each measures about (1.75) or (2.00) inches in diameter. Keep in mind that the size of each ball varies slightly as these are natural products.
