There are seven men on a bus. Each has seven backpacks. Each backpack has seven cats, each nursing seven kittens, all on the bus. How many legs are on the bus? (This is not a trick question. The driver has stepped off to use the facilities; the cats should have. All animals and humans have the normal number of legs.)

Lets see..
7 men=14 legs
7 backpacks with 7 cats each, each backback as 7 cats=28 cat legs. 28x7=196
next is the real kicker..7 cats each nursing 7 kittens. There are 49 cats in the seven backpacks-nursing 343 kittens,
I think there needs to be an additional x 7 in the second one -- each man had 7 backpacks!!
Sorry about that, I hit reply before I finished.

next is the real kicker..7 cats each nursing 7 kittens. There are 49 cats in the seven backpacks-nursing 343 kittens, totalling 1,372 legs. So altogether, it totals 1,582 (14+196+1372)
You wrote, "7 backpacks with 7 cats each, ..."

But there are 49 backpacks -- 7 men, EACH having 7 backpacks ...
OK..here we go again
please correct me if I am wrong
7 men=14 legs
each man has 7 backpacks each with 7 cats each.each one of those cats is nursing 7 kittens.

56 cats and kittens to each backpack-392 cats total per man
392 x 7 = 2,744 x 4 is 10,976 + 14 is
10,990
