Is the smell of burnt food toxic?

[happycat]

Came home a few minutes ago to find the strong smell of burnt food in the house. Apparently my mom had been reheating some rice on the stove earlier today and she forgot about it because she was on the phone, and when she noticed the burning smell she turned it off.
That was around 4-5 hours ago and yet it still smells pretty bad in the kitchen and living room. It doesn't smell in Kirby's room though. She turned on the fan and opened his windows when it happened too.
Would that be considered toxic to Kirby? He seems just fine 5 hours later. I'm still concerned though because it smells. I had trouble finding much on google though.
Thanks

The fire alarm is not a timer.

I'm aware
This is definitely not a regular occurrence, don't worry.

Not the smell, but the chemicals causing the smell can be, depending on what was burning, the proximity and the length of time the exposure was. Keep an eye on him for respiratory problems, but after this much time I would relax pretty much and just keep the door to his room closed until the house airs out more.

Now I'm honestly confused. If JUST the rice was burning, what chemicals are involved? I understand the danger of overheating a non stick pan, however, sometimes 'stuff' burns on the bottom of any pot/pan, even with the temp being set to low.
