There was a cat named Vaska, too. If memory serves, Vaska was Olga's cat.
Bingo, that is the one. Yes, she was Olga's cat.
I wonder if Tatiana had a cat?
I am not an OTMA expert, but I believe that she did. Maybe the cat Tatiana was caressing in the photo above posted was her. How about Maria, did she have a pet?
IMO, Nicholas' children loved the pets. Which reminds me of a saying - " We can judge a man's nature by the way he treats the animals. "
