Teenage humans - can they get obsessed with cats?

Dear George,
My name is Schwartz and I have a family of human pets - adult male, adult female, teenage boy and 11-year-old girl. They are all reasonably well trained and depend on me for affection.
It's the teenager who is worrying me. He has always been fond of me but now he shuts himself in his room with his computer and me. He has stopped vocalising to his family and spends most of his time online looking at cat photos and cat videos. Occasionally he looks at photos of naked humans, but seems to prefer cats. Is this natural? And does it matter?
Yours
Schwartz.

Dear Schwartz,
I can reassure you that watching cat videos and photos is normal for a large proportion of the human population. Scientists (I am not joking) have declared that this is good for humans and is particularly valuable for procrastinating with tasks. Your human is probably using cats as a way of not doing his homework. Watching too many naked human videos may be bad for him: so cat videos are preferable.
If you feel that he needs a rest from his computer, you can put into effect an online interruption and deterrent programme. Simply jump up on his desk and interpose your body between him and the screen. Do this is a cute way so that he responds to you with petting and eye contact.
If this doesn't work, then you need to do stronger measures. Walk up and down the keyboard, that rectangle which has small tabs on it. Or just stand motionless on it. You will see that  series of pleasing mouse tracks appear on the screen, interrupting his work there.
Finally if all else fails, lie flat on your back on the keyboard and wave your paws in the air. No fully functioning human can resist this. For me it works every time.
Yours
George.
PS. Scientists have discovered that adolescents get on better with their pets than with their siblings. Look here.. So your teenager is normal.
