As a result of someone's negligence, mutant rats appeared in Saaremaa that are not afraid of people
A resident of the village of Kalma in Orissaare discovered variegated gray and white rats eating pig food and ignoring the appearance of a person.
Some time later, the rats bitten a rooster, and 15 rats fell into the set traps, and 11 of them were variegated. The cat refused to chase the rat hiding in the wood, writes Oma Saar.
The same rats were seen in other places, a few kilometers from Kalm.
Andrei Milyutin from the TU Zoological Museum, who studies rats, doubts that these rats are the result of crossing free laboratory rats and wild grays, since, in his opinion, the genes of laboratory animals when crossed are dispersed in a large population, moreover, in Saaremaa so many places where laboratory rats are kept.
Laboratory rats differ from wild ones in the absence of fear of humans, and the transfer of such genes to ordinary gray rats can be extremely dangerous, the scientist explained.
