Many of you have likely heard about a tiger which escaped from the
San Francisco Zoo and then attacked some people.

http://en.wikipedia.org/wiki/San_Francisco_Zoo_tiger_attacks

The biomechanically relevant data are:

On Thursday December 27, the zoo retracted its prior claims that the
grotto's moat wall was 18 feet (5.5 m) tall, after officials measured
it and found it was actually 12.5 feet (3.8 m) tall. The AZA
recommendation for big cat enclosures is a moat wall of 16.5 feet
(5.0 m). Tatiana's feet were also found to have concrete chips,
suggesting that she climbed out of the moat using her claws on the
wall.[18]

The biomechanical aspects are intriguing and some media people have
asked for my opinion/reaction etc.

The key questions are: how high can a tiger leap and how well can a
tiger climb a vertical concrete wall?

I have studied some crazy animals but never a tiger and never a maximal jump.

I suspect that some of you have more informed opinions or maybe even
some references.

Here are some small cat papers
