Thank you for looking! (*^-^*) The hooks are random. ○ You can fix it in your favorite place with the hooks. ○ For rabbits, they can do their favorite digging, which helps with lack of exercise and stress relief. ○ You can spend time safely without worrying about slipping on the smooth surface of a heated mat. ⚪ Why not try it once for a rabbit who is scared and won't get on the heater? ○ It can be washed. 〈Size〉 Approximately 40cm x 28cm 〈Material〉 Polyester ※ Heater not included! ※ We hope you like it.
