HELP MY SICK CATS

:-/  I am struggling to take care of all of my responsibilities. I have two cats one names MooCow and Mamma's. They have hook worm and had them when they were given to me apparently. I was not told anything. They both are about 6 months old and are very skinny and look sickly. They eat and eat and eat but they never get any fatter. I have no way to take them to the vet and I have vouchers but only to get the fixed. I'm scared they will take my animlas because of a law that claimas they can keep your animal if you cannot pay. I'm so scared I have read all the things that could happen to my babies and everyday they are more and more at risk of even death. PLEASE HELP. ANYTHING WILL HELP. https://paypal.me/LHaley592
