Is it weird if pets keep disappearing under my niece's care?

My niece is a sweet 9 year-old girl. However, would you find this weird? Last week was the 4th pet that disappeared under her care. She said the same story as last time. She said the cat ran away while she on her tablet playing games.

There aren't any complaints about her at school. Though a classmate claimed she once said with a smile ''Accidents can happen after all. Even if it wasn't, they won't believe you''.

First it was a hamster that goes missing, then 2 puppies and now a cat. Pets go missing only under her care. Is this weird?

She likes taking care of a pet but it ends up disappearing.

This is the update now:
I'm afraid our worst fear has been confirmed. Her relative played her role so well that she fell for the set-up. She would throw the pets on a black bag and into the dumpster. If it was a bit larger, she would make it tired and drowsy (she didn't amitted how but said she did that) first and then throw it away. Her relative played along, said she'll throw the kitten herself and instead gave it to a neighbor to care of it and called us right away. The kitten is save.
