The invention relates to a veterinary technician, and more particularly, to the means of trapping biological objects. The network consists of two columns and a network fabric, made in the form of a rectangle or trapezoid. Two string attached tinctures and threaded through extreme long sides of the cell network fabric, and extreme short sides of the cell network fabric threaded through the stand or attached to them. Relationship network of the long sides to the short is in the range from 3 to 15. In the second and third embodiments, the string is made of a material having high elongation, e.g., rubber. The fourth embodiment of the lower string is attached to the lower parts of the pillars, and at the ends of the upper bowstring mounted slip rings, put on the rack. Moreover racks diameter smaller than the inner diameter of the slip rings. The fifth embodiment is characterized in that the lower ends of the bowstring is fixedly secured in the lower parts of the uprights, and on the upper ends of the bowstring mounted slip rings put on the rack, and the short sides of the extreme cells are threaded through the web network rack. The sixth embodiment is characterized by a fifth in that the lower part of the outer cells of the short sides of the network fabric is fixedly mounted on racks. In the seventh embodiment, both of the string are fixed to racks and installed in the network corners slip ring locking mechanism to the uprights. In the eighth embodiment of the upper stringer is fixedly mounted on the racks, and a lower bowstring is fastened to the lower corners of the network, the network in the upper corners of the seal ring fitted with a locking mechanism to the uprights. On the underside of the string can be installed loads. When working with a network catchers unwound web block the possible path of movement and in a certain way tipping rack, moving the sliding ring changing the tension of the network etc. provide trapping the animal in the network.
