Yoll was invited to appear in the children's show "Yeralash". The role was not complicated - it was just necessary for her to turn from a stuffed owl into a living owl then sit to turn her head. Since she was quickly fed up with turning her head, the help of a cat was used for takes, which was also filmed in the plot. The cat was a little scared by the eagle-owl, but quickly got used to it, like Yoll herself, who was tired of paying attention to the cat.
This eagle-owl in this situation is not dangerous to the cat at all. Yoll does not attack cats, she only hisses at everyone who is in risk of accidentally hurting her. This is just to warn others not to get closer, and does not mean that she is going to attack. There was no risk of conflict between the two animals.
