Fridge issue!

Fridge issue!

Recently a big wet spot showed up by my fridge. Our kitchen, unfortunately, is carpeted and the smell of the liqud smells like urine! Now, I first suspected my cats but in the 3 years I've lived here, they've never peed on the rug out there. The only places they have peed other than the litterbox was on the small rug in the bathroom (after I changed to a litter they disliked) and on the bed in a pile of clothing (which I heard is common). I am pretty sure the leak is coming from the fridge and not my cats. Anyone else experience this? We did notice the ice was not filling up in the icemaker. My boyfriend called the landlord and he instructed him on how to shut the water off to the ice maker. but the rug seems to still be very wet. When I soak it up with paper towels, it's mostly clear and doesn't smell strong. I've also been getting a lot of headaches recently, related?
