Things that go bump in the night

First, you hear the tortured mewling. Then spy the erratic movements out of the corner of your sleep-filled eyes. More like shadows.. What time is it? Where am I? Who's there? WHAT'S THERE? Then a sound like malicious laughter but with a horrible pain-filled quality. Closer. CLOSER... then it jumps...no, leaps onto the bed with a speed and purpose as if moving in for a quick kill. It happens so fast, you have no time to scream. 

"Oh, it's only you" he says with quivering voice while his pulse pounds in his chest.
You just came to keep me company. He reaches out tentatively a receives a raspy lick and contented, rumbling purr.
What pretty eyes you have. And so friendly...but, wait, is her tongue forked?
