Cats may not be a problem there but in this study they certainly are the problem number 1.

------ The excerpt from the study about mortality ------------
As of October 2019, we have the following does and yearlings (fawns from spring of 2019) collared in our study areas:
Boundary: 22 does, 5 yearlings,
Cache Creek: 26 does, 3 yearlings,
West Okanagan: 27 does, 12 yearlings
Generally speaking, our deer in the Boundary have very low survival rates, whereas Cache Creek have high survival rates, and the West Okanagan is somewhere in between. Survival of adult does after the first year of the project was 69% in the Boundary, 95% in Cache Creek, and 83% in the West Okanagan. We will have a better idea of fawn survival by spring of 2020. The breakdown of mortality sources in our study areas are as follows:
Boundary Mortalities = 22
Cougar 15, Canid 1, Coyote 1, Drowning 1, Apparent Grizzly Bear 1, Unknown 1, Vehicle 2
Cache Creek Mortalities = 7
Black Bear 1, Cougar 2, Coyote 1, Unregulated harvest 2, Health 1
West Okanagan Mortalities = 15
Cougar 5, Apparent cougar 3, Coyote 1, Predation 1, Starvation 2, Unknown 1, Vehicle 2
---------------------------
As you can see 21% of collared does and yearlings were killed by Cougar in Boundary region\West Kelowna around 6-8%,
But in all cases Cougar is number 1 predator issue affecting does and fawns. NO fawns no bucks, simple as that.
So my question is where do you draw your conclusions from?
