I used to have about six in my yard, during the monsoon season they swarm the streets. I love toads too 
). Floppy survived for more than a year with severe disfigurement of the spine.That seems like a pretty typical lifespan for a rat. Unless I'm missing something here.Unfortunately I have no pictures to prove he exited. But last year a girl gave me her four year old rat. he lived with me for another six months before croaking. I think I may have accidentally killed him. He was the ugliest rat I have ever seen.
