But to get back to Beatty's abilities with cats, Alva Johnson told the following story. Early in 1951 Beatty's prized rollover and spinner "Sleika" was killed at the Detroit date. Beatty ordered two new adult tigers from Henry Trefflich and these were shipped directly from India to the show, arriving on the lot between performances.

Beatty immediately had them put in the arena and went in with them- and in short order was able to get enough of a response from one of them to realize he had a rollover. He came out of the arena laughing and yelling, "I've got one!" and in a few days "Saber" debuted as the rollover tiger and remaining in the act for years.

To an old billposter this sounds a lot like a pretty skilled cat man at work.

I wonder what statement solidified Ole Whiteys belief that Beatty was a pretty skilled cat man. The one where the tiger was killed in Detroit, or the one where he taught a new one to roll over in short order.
