Grammar check for sentences about burrows — for a 6-year-old

Original sentences:

2. A burrow of a skunk is much simpler.

Corrected sentences:

1. A prairie dogs burrow has air vents, a bedroom, a nursery, and a toilet area.

2. A skunks burrow is much simpler.

1. Possessive form: Instead of saying "a burrow of a skunk," we say "a skunks burrow." This is shorter and sounds natural.
2. Comma in a list: When you list three or more things, its clearer to put a comma before the word "and." So we add a comma before "and a toilet area."

One sentence version (optional):

A prairie dogs burrow has air vents, a bedroom, a nursery, and a toilet area, while a skunks burrow is much simpler.

Short explanation for a 6-year-old: Use "skunks" to show the burrow belongs to the skunk, and put a little pause (a comma) before the last thing when you say three or more things.
