At such high voltages and considering in a human only 0.050 amps can disrupt their heart, there could "possibly" be enough voltage and resultant current flow from any phase to that wooden pole to kill the cat dead if he gets across the same, but that's dependent on the poles moisture and materials (IE its conductivity). I'm assuming a grounded Y HV primary distribution scheme.
There's high voltage across those top three phase to phase wires but their separation distance would make it hard for the cat to get line to line voltage.
At one facility I designed for the HV Primary distribution was 12,470 Y 7200 Volt Three Phase Four Wire.
To receive a shock the cat needs to be across high voltage IE NOT just one live phase, and such exists
Line to Line,,,,,,,,,,Line to Neutral,,,,,,,,,,,,Line to earth ground assuming that's an earth grounded Y system

Today's Featured Article - Usin Your Implements: Bucket Loader - by Curtis Von Fange. Introduction: Dad was raised during the depression years of the thirties. As a kid he worked part time on a farm in Kansas doing many of the manual chores. Some of the more successful farmers of that day had a new time saving device called a tractor. It increased the farm productivity and, in general, made life easier because more work could be done with this 'mechanical beast'. My dad dreamed that some day he would have his own tractor with every implement he could get. When he rea
