The characteristics of this kind of small animal cage are small size, light weight, easy to carry, and easy to clean and take care of. For small animal cages, generally the wire diameter of the iron wire is not very large, and the thickness of the plastic is relatively thin, so it cannot be "violently" when used, otherwise the cage will be desoldered or the plastic will be cracked under "destruction". 　　

Most of the small and medium-sized cat cages, dog cages and fences are made of pure iron wire butt-welded, and the wire diameter is generally between 2-5mm. Of course, the larger the size of the cage, the thicker the wire will be, because the larger cage needs to bear more force.

Many luxury cat cages, dog cages, parrot cages, bird cages and bird cages will use iron square pipes. Luxury cages use iron square pipes as the frame of the cage body, and then solder iron wires on each side. The square tube cage is characterized by a more beautiful appearance, a stronger cage body, and more surface treatment methods.
