Who ever put that chart together needs to learn something about cats in Texas. The skinny feral cat currently asleep on the bed weighs in at 15 pounds, not 5-11. And the local bobcats are likely in the 25- 40 pound range.
Everything is bigger in Texas! :-)
I was about to say that the last three house cats I’ve owned were all in the 18-22 lbs (the males) and 15 lb (for the female) range on weight. And the pelts that I have seen from TX bobcats tells me that 30-35 lbs +/- is probably about right.
