Does anyone know what this could mean?

Ok, well my cat Jinx is pregnant and dues and day now and she started acting really weird to my cell phone, just mine, whenever it rings or I get texts she meows and it and rubs against it and trys to bite it. I have a little video of it, not great and the guy who was recording it is dumb and doesnt like cats. But what could it mean?

Maybe the particular tone you're using either irritates or sounds high pitched enough to sound like a kitten to her? Only idea I can think of. And as for why she only does it with your phone - it smells like you, familiar.

but she does it for any sound coming from the phone, all the ring tones plus the little beeps
