The actors are too busy to properly care for the ageing pet and so Pratt took to the site to find Bella a new owner.
In a recent post, he wrote, "Anyone in the LA area want a cat? Full disclosure, she's old and prone to accidents. So sweet though. And was in (the movie) Stuart Little. (literally)... She is very sweet and needs a good home. We have pugs (dogs) and she's too old to deal (with them). She needs one on one attention."
But his thoughtful actions have provoked a storm of protest - and he has even received death threats for using the social networking site as a place to search for a cat caretaker.
In a post on his personal website, the actor writes, "I found my aging (sic) cat a god d**m loving home! Ease up with the death threats for heaven’s sake!...
"Bottom line, and not that this is any of your f**king business weirdos, but my wife and I want to start a family and we ABSOLUTELY CANNOT have an animal that s**ts all over the house. Sorry. If you are a parent you will understand. And if not, that probably explains why you have such a hard on (erection) for cats. Just sayin’.
"I mean, really? So what I used twitter to give away our pet? I have some people who follow me and I thought maybe somebody would be thrilled to have my old cat. And guess what… Somebody was! Her name is Meghan and as far as I could tell she is a perfectly reasonable, sweet and friendly cat lover.
"I met her to make sure she wasn’t a weirdo before handing the cat over. She is from the same area of the country that my wife and I are from. She has no other pets and was fully aware of Bella’s problems. And despite all that, still opened up her home!... So please! Stop with the harassing tweets! That s**t affects me. I’m human."
