The ball was filled with treats and passed the young cat, who immediately showed interest and the round Something that smelled so delicious, repeatedly hurled into the air. That something then struck several times on the hard tile floor and broke into 3 pieces apart. On closer inspection of the items, unfortunately I had to find that the transparent hemisphere already showed cracks and therefore everything was disposed of as a precaution to avoid injury in humans and animals. It is positive that my cat mastered their stated object in a very short time with flying colors and has captured the treats. On the downside, the ball was apparently produced only with a minimum durability of 5 minutes. Conclusion: Endurance test failed and why not buy recommendation!
