Making up a scenario to illustrate a point is not whataboutism. I do not consider it likely, the idea was to merely illustrate that in high density areas (you know, where most of humanity lives), the number of cats is such that allowing them all outside is simply not an option.
And if solicited advice is the only advice we are allowed to give, how exactly are outdoor cat owners to be dealt with? Do we just sit around until they randomly look up how long their cats could be living?
