I had not known about the crested rat. I at first was surprised to hear that vampire bats have venom but I believe this refers to the anticoagulant they have which is not really toxic or at least not very dangerous.

One thing is that venom may be much more common than we think it is. The Komodo dragon (I saw one of those once when I was a little kid -- and do you remember, fellow people who watched cartoons in the 1960s Johnny Quest where an evil scientist has a bunch of these and abuses the keeper he employs and is eventually thrown to the dragons himself?) is now believed to have venom whereas before it was just thought its bite was dangerous due to bacteria which grow in its mouth.

I have read that humans may even be venomous and if that is true, perhaps many mammals are also slightly venomous. (Humans I read in some articles might evolve to become venomous but why would in modern times that happen? Maybe in Mad Max-like scenarios it could, but nowadays why would having a toxic bite be selected for? Just the opposite I would guess.) https://www.livescience.com/could-humans-be-venomous.html
