Riddle me this

From the moment I arrived here in foggy, windswept, beautiful Cornwall, I had one phrase swirling around in my head.

"As I was going to St. Ives/I met a man with seven wives..."

That's because the real St. Ives (also see: skin product) is about 15 miles from where I'm staying, in Penzance (also see: Gilbert & Sullivan, "Pirates of"),

For the first several days I thought I was going crazy. I had no idea where I'd heard that phrase before, and I didn't know the rest of the rhyme (although I was pretty sure there was more of it.) Finally, I resorted to the internet, and because we pretty much live in a Hive Mind society these days, a simple 30 second search got me the following:

As I was going to St Ives

I met a man with seven wives

Each wife had seven sacks

Each sack had seven cats

Each cat had seven kits

Kits, cats, sacks, wives

How many were going to St Ives?

I have no idea where I would have heard this rhyme, but I can imagine it was probably a nursery rhyme I learned (the Brits here would say "learnt") some 20 years ago that was floating around waiting to be rediscovered a decade or two later. The brain's capacity for memory is occasionally astounding.

By the way, can you figure out the answer to the riddle?
