I did not realize that made a difference to their energy levels, but it makes sense.

My two three months when I got them August 2015, so they're getting close to being two years old now too

Okay for cats is 2 years fully grown or are they still pretty much kittens at that point? I've only ever had adult cats.

Yup. Two years is full grown

Aha, thank you! So Mop is getting close to teenager-hood, then?

Yeah
Hopefully he won't spray everything in sight

They mostly do that when they are around females in heat, right?

It's territory marking
They're much less prone to do it when fixed, and we, females spray too

So it's a thing they do as adults but not as kittens, because kittens don't have territory. Got it! I think. >.<

Yeah
