Okay, so I'm sittin here next to loki & I hear this sound, & for the life of me I could not figure it out. Almost sounded like he hiccuped, & just before that i was hearing "pfffffffft" sounds kinda like a hiss but not really, here I am thinking omg he's comin down with an RI just not bubles or mucus. Low & behold, the lil brat was FARTING! The "hiccup" was from him havin a bm! lol. I feel like such an idiot but am so glad thats all it was! Whew. I even picked him up & checked him all out and everything! lol. Go figured, I'm just too worried bout my lil Loki.
