I guess it’s okay to name your pet something wacky. I’m not sure most pets understand the name you’ve given them. It’s more likely that they’re responding to a “series of sounds” that your making (but then again, isn’t that what we’re all doing). I guess what I’m trying to say is that they don’t really have any context for the name you’ve given them, so they probably don’t take a wacky name too personally…
