Hi Craig ,
Food availability and the type of prey defines growth rates and possible increases in size . IMO.
If a cat has been eating small prey items , ie mice or skinks etc then its more likely to be smaller .
But say if a cat feeds on rabbits or banditcoots as its main pereference is for larger prey .
If those cats breed a few generations living on that diet of larger prey the benefits will in time produce larger cats.
Also seen huge dingos obviously with domestic dog in them.
But what the hell , large panthers etc are exciting to hear about ...lol
Im curtain i could ID the real perp of any of these so called panther kills , by the evidence of how the animal was attacked and killed and the tracks or spoor around the area of the kill.
A true bushman would more than likely have shot a panther or puma or leopard by now if they were really here.
Excellant bow hunters and rifflemen are out in the bush all the time etc.
They would drill a big cat in a heart beat then show it off ????
Also i did not even bother to watch the video in the first post , untill just now.
The whole video is self explanatory.
Domestic cats do grow a lot larger than in the wild.
If any of these eye witnesses who owned dogs had really seen a panther they would also be telling the story of how terrified there pet dog was after a close encounter or if the dog even so much as smelled a panther.
Its widely known amongst hunters that domestic dogs are frightened of big cats. Unless a dog is trained otherwise.
And these eye witnesses are lucky there dogs are still around because big cats love domestic dogs for a snack etc
Of course there are hounds that are trained to hunt big cats in many countries. If a real outdoorsmen saw a big cat, im pretty sure dogs could be trained to tree these big cats . Its how problem big cats ie mountain lions are dealt with in the USA . etc
Mountain Lion Attacks from 2001 to 2010
The other thing is that a moutain lion or a black panther ie melanistic leopard are not magical creatures .
They can be hunted and captured or shot quite easily by a experianced hunter.
So if there was big cats running around they would be caught and shot in know time .
