The International Feline Federation (FIFe) has weighed in on the Ukraine crisis, banning Russian-owned cats from competing in its shows as a sanction for Moscow’s military attack on the former Soviet republic.

“The FIFe executive board is shocked and horrified that the army of the Russian Federation invaded the Republic of Ukraine and started a war,” the Paris-based federation said on Tuesday. The group added that it “cannot just witness these atrocities and do nothing.”

As a result, cats belonging to Russian residents will be banned from entry at FIFe shows. In addition, no cats bred in Russia can be imported and registered in a FIFe pedigree book, the group said.
