Hey Forum

I have two questions. The first is about humidity. Right now, the digital hygrometer I'm using says the humidity is ~85%. Ever since summer started, the humidity in my snake's cage has spiked. A couple months before summer, I followed instructions to covering the terrarium mesh with aluminum foil to help with heat and humidity. The heat is fine now, but now the humidity is too high. What should I do?

My other question is more of an affirmation. A couple weeks ago, I tried feeding my ball python a f/t small rat. It didn't take it (it smelled the slightest over-done, so I thought that was why), but because I wasn't completely sure - small rats were not giving my rat a bulge anymore when eaten - I bought a medium rat. It took the medium rat instantly. I tried a small rat again yesterday, and no luck. Can I safely assume it will no longer take small rats? I still have a bag of 3, so I thought to try and use them so I don't have to return them.
