I've made Elizabethan collars for those struggling with self-harming in their pet birds. Made with 2mm thick high-quality felt (※a very rare, sturdy type compared to commercially available ones) 5 for 1000 yen 【Product Description】 I've created handmade felt Elizabethan collars to help with feather plucking in lovebirds. I use thick 2mm felt, which is rarely found in commercial products, so it won't bend or lose its shape. As someone who has struggled with feather plucking in my own lovebird and tried various solutions, I found that a felt collar with this shape and firmness was the most effective. Based on my experience, I'm making these to help others facing the same problem. 【Sizes】 You can choose from two sizes to suit your needs: 8cm and 10cm in diameter. The sample in the picture is 8cm. You can also choose with or without a hole. The hole is 2cm in diameter. For my lovebird, I make 2mm cuts in 4-5 places around the 2cm hole. It's very sad to put these on cute birds... but sometimes they pluck until they bleed, so I put them on until the wound heals. If you want to put it on only in the cage and take it off during playtime, a snap closure is a good option, but please check the images for the added thickness of the snap. ① 8cm diameter, no hole ② 8cm diameter, with hole ③ 10cm diameter, no hole ④ 10cm diameter, with hole ⑤ 8cm diameter, with hole, with snap closure +500 yen ⑥ 10cm diameter, with hole, with snap closure +500 yen If you want ⑤ or ⑥, you need a price adjustment, so please do not purchase immediately.
