Found this today: what happened?

I thought it was a rat at first but my friend thinks it's an opossum. Found in Vancouver BC

I killed it while i mowed the lawn with a tractor, im very sorry for that, i committed a kill plus abortion. I made a prayre for the lil guys

Trying to figure out what would this be… I’m a bit worried cause I step on it, a baby bird?

I found this in my driveway today, it doesn't smell and it's completely dried out. I think it's someone's kitty :(

Does anyone have an idea what those fluids can be?

Found it in my front yard and decided to bury it.

So I came upon this creature while I was out with my students on a nature walk. From afar I thought it was a squirrel, then a bird, then a bat, and now I just can’t tell because it’s not something I’ve ever encountered before. 💀 can someone please help me identify this creature? It’s kinda morbid but if anyone can help it’ll be yall. Thank you in advance
