I should possibly clarify, when I said "dirties his water" I mostly mean he's clearly going in there somewhat often, its just not as often as he was previously. Like, he wasn't constantly soaking, but he was in the bowl more often then he was before this all started.
And yes, I'm definitely starting to realize that. I'm not sure why it's only just now started having issues holding in heat, but I'm not a fan. And I will most definitely keep you all posted! Thank you!
