The Sparrows do make a racket, often during feeding time.
A young Sparrow fledgling has to be fed every hour by one of its parents for quite a while until they are fully adult and able to fend for themselves.
You may notice the expression of the 3rd sparrow on looker.
Interesting story of sparrow parenting skills.

I agree with you since I like dogs and cats a lot.
