Is this something a landlord has to fix?

We live in a rental home, have been here since February (lease started mid January though)
We have some issues with the home, we knew moving in it was an older home that needs lots of work, I’m talking minumum 60k-80k. We actually redid the electrical (it wasn’t grounded at all, we didn’t feel that was safe even with renters insurance)

My complaints:
The oven smells like urine when it gets hot. I’m not even making this up. I’ve googled and apparently it can mean mice, but we have two cats and have never seen a mouse, but the cats practically live in the kitchen staring at the dang oven so I just know we either have them or had them and they will never see the light of day.
So I’ve complained twice, and both times they assume our oven is dirty with something…like I haven’t thought to clean it??
But I informed them about the cats being obsessed so they said they’d send someone over to pull the oven out to check behind it.
Never happened. (it’s a real estate company in charge for the owners…)

My biggest issue is the unfinished natural wood floors, I have a crawling baby who keeps getting splinters in his hands, my feet get them and my 3 year olds feet is filled with them (he won’t let me get them out)
I’m about to take the 3 year old to the doctor to get the dang splinters out and so I have it on record that this is a serious issue

Do they have to do something about the floors though or is this a just “grin and bear it” situation since we’re renting?? I’m just curious if we have any right to even complain about it.

(and no, moving is not an option. the rent we have is amazing for the area..best school district and extremely nice neighborhood.)
