Is this normal

Hi I was wondering if anyone know what this is or has the samee thing going on as well. Every time I go to warm up my car I hear this sound coming out of the engine. It sounds like as if you were vacuuming your rug then later it goes away. Does anyone know what this sound is and if its normal?Thanks in advance

The gist was that it's a normal part of cold start operation - something to do with the emissions system. Sorry to be vague; it's been over 5 years since I asked about it, and I don't remember the details.

My mice still owe me last month's rent.

haha, but yeah, I noticed the same thing. I started my car the other night, and stood outside of it and heard the noise, but it went away like after two minutes. Pretty cold out.
