The ONF determined the state of the thermal insulation of housing and communal services in the Russian Federation with the help of freezing cats 
there are the greatest problems with the thermal insulation of utilities communications. They were able to measure the degree of damage to communications with the help of cats that warm themselves on pipes in the cold season, according to the organization's website.
Cats freezing on pipes have become the unit of measure for the rating of cities. In total, more than 220 thousand pets can warm up on communications in 64 regions of the country in winter, which is equivalent to at least 66 kilometers of communications. The leader of the rating was Pereslavl-Zalessky in the Yaroslavl region – in one of the microdistricts 5 thousand meters of damage were recorded, where more than 16 thousand cats can settle. A similar figure was recorded in Ryazan – more than 16 thousand animals per 4.9 thousand meters of problem pipes.
The third line of the list was taken by the village of Talaya in the Kemerovo region, where more than 11 thousand cats can occupy 3.5 thousand meters of pipes. Below are Perm (almost 3.2 thousand meters for more than 10 thousand cats) and the village of Konstantinovsky in the Yaroslavl region (2.5 thousand meters of heating mains for 8.3 thousand pets). The sixth and seventh lines of the rating were taken by Barnaul in the Altai Territory (2.75 thousand meters for 7.5 thousand cats) and the city of Lermontov in the Stavropol Territory (about 6.7 thousand cats per 2 thousand meters).
Top- 10 of the list closed the village of Game in Udmurtia, where 3.3 thousand cats can be accommodated in less than a kilometer of damaged pipes, as well as the village of Svetly in the Tomsk region – 950 meters of problem pipes for almost 3.2 thousand animals.
In September 2021, community members of Housing and Utilities Control determined that the engineering infrastructure, on average in Russia, was ready for the heating season at an estimate of 3.79 on a five-point system. More than 30 percent of respondents indicated problems with heating networks in preparation for the autumn-winter period.
