Still working on some of the clues, but I may have a lead on some.
Don't get sidetracked - this is probably Denver's first
I believe that this is referring to John Denver.
Don't get side tracked
I thought of train tracks and All Aboard! was John Denver's last album
This is probably Denver's first
I think refers to his first studio album "Rhymes and Reasons" which has a song at the
beginning of the B side titled "Yellow Cat" maybe to do with the title of this post
More thoughts on this clue...
Could the clue be referring to not getting sidetracked by not overthinking it? is it as simple as Denver's first letter or syllable?
Another idea is that it could be John Denver's first name which is Henry. (@hdsdv confirmed that John is correct)
Using the logic that @Ahmed pointed out, we get Denver's first name by omitting the punctuation and just reading the clue straight through. Applying that same logic, it could be the cartoon bear that that loved honeydew. Possibly Yogi Bear because he ate human food.
Continuing this logic further would take "sleep" and "in" to give us sleeping
Then the 3 words we have are John, Honeydew, and Sleeping. Pairing two of these (John and sleeping) with the title clue (cat) could be Garfield?
Name the cartoon bear that loved honey.
I think this is Winnie the Pooh or maybe Baloo from The Jungle Book...
I found a wiki page of fictional bears. Maybe this can lead to something.
Reading between the lines this could also be meaning that the cartoon bear is named John. Little John from Robin Hood is the only one I know of. And he slept in Sherwood Forest. Then the last line could mean something like "of course" = sure and "woods" = forest... Just putting my thoughts out there, but translating that to a place on google maps didn't yield any significant results. Sherwood forest contains no lakes and lake Sherwood in West Virginia wasn't quite a match to the picture.
Do you remember him, or at least where he likes to sleep?
Not much here other than if it's Winnie the Pooh, he lived in Pooh's Corner.
In the woods! Of course.
Just a shot in the dark, but could be something to do with golf. "Course" like a golf course and "woods" as in Tiger Woods (also brings up the title again with the big cat thing).

In hint #1 "... any hints I might have left lying around." Could be like "... any hints I might have left lion around."
Solved!

Honeydew is a type of Mellon
