Why kill the pets?

Moo...so if there was no violence it would be carbon monoxide or poison/of I guess

That was my assumption too.

Why kill the pets?

Why does a family annihilator do anything? Some of these people do that. Xavier Dupont de Ligonnès killed the dogs, too.

Apparently there was a note.

Yes he did. It just makes it even sadder.
As for why? I'm going to purely speculate and say it sounds like the children had complex needs and there may have been financial difficulties. The strain probably took its toll. There's always alternatives. These are the actions of a desperate person.
