Its ok Kirsten.. Your baby is having a hard time getting a HairBall up & out.. Try giving her a Raw Egg (scrambeled in a bowl) & see if she will eat it.. My Half Pint does this with spitting the white foam & I will give her a egg & all is better.. Now if this baby continues does it thru out hours of time then rush her in to a Vet.. Let me know ok..
