Well there are pet translators these days that measure and analyze the sounds they make, to tell you what they're saying; so perhaps occasionally, if we mimic them, they might be like: WTF is the human talking about?
On that note: There's an Australian man who says he can understand the language of crows, I once heard him give a few examples over the radio, translating common words like 'hello', 'goodbye', 'yes' 'no' etc. According to him, crows even have names.
