Not for *****'s - Lift Airline

I have asked Lift Airlines to explain to me why they allow small dogs in cabin but not cats on board. I've received the usual corporate fob off responses like "red tape, permissions, blah blah", together with a pile of platitudes "we do love cats, we have cats of our own, blah blah." So I did some research, ACSA are not the culprit. In 2019 they allowed cats on Khulula flights. IATA animal centre, said they don't discriminate and do allow cats on board. That leaves Global Airlines operating as Lift as the company making the ************** and I want to know why little dogs who are far more likely to be a bother in a closed confined space, than cats who thrive in those conditions. Both excrete, both woof or meow, both have hair that people are allergic too, both require food and water, so what POSSIBLY can be the reason cats can't fly in cabin???????
