I'm not sure I really want to know what my pets are saying.
"Buy me different food"
"Take me out NOW"
" MOVE I want to sit there"
"Mom' tell the others to leave me alone....I want to sleep"
"Make that Kitten stop playing with my tail"
"Feed me Feed me Feed me Feed me"
"Pet me pet me pet me"
And that I already know they are saying.

It would be nice to hear "I love you" though, even though I already know that too. That's shown in other ways without a translator.

So I think I"lltake the money and buy them a toy or two instead.
