What is good for hair ball hacking?
My cat is 4 years old now.
Up until the past two weeks, I've never seen her hack like she's trying to get a hair ball loose but that seems to be what is going on now.
She has, as all cats do, thrown up every now and then, but not much.
Now, she has this hacking going on 2 or 3 times a day.
I remember my dad used to give our cats a little vaseline petroleum jelly to help them get the hairball down, instead of having it come back up, but I don't know if he knew what he was doing or not, or if it is even good for the cat or not? The cats used to lick it right off his finger like they liked it, or knew that it would help them.
What do you suggest for this hacking cat?
