There are many great options for PVC/ Plastic cages out in the market. Some companies are overpriced in my opinion others are fairly priced. Animal Plastics is a great company with great products and excellent customer service! I also like All American Cages. They are well made/packaged PVC enclosures at a terrific price! I will list a few great companies that I’ve heard great things about or personally have had a great experience with…
