My new kitten I got today is 7-8 weeks old and I can feel her ribs on the side but shes normal on her tummy....not round...just normal....could she have worms? I am getting her dewormed on the 29th....just wanna know if it sounds like she has worms...plus someone mentioned that puking up saliva means heartworm....she did that earlier...but only once. I think it was cuz she hadnt eaten for a few hours tho
