Using these perches is easy. Just use the secure metal hardware to attach the perch to your bird's cage bars. Make sure it's firmly attached so your bird can use it safely. As for the flavors, your bird will surely love the strawberry - banana and pineapple - banana options. It's a great treat and a healthy addition to their cage. When it comes to maintenance, check the perch regularly for signs of wear and tear. If the cuttlebone starts to break down too much, it's time to replace it. Also, keep an eye on your bird's feet, beak, and claws to see if the perch is having the desired effect. Note that these perches are made for birds, so keep them away from other pets. And always ensure the perch is clean before putting it in the cage to avoid any health issues for your bird.
