I know its good to adopt a pet from the shelters we have done this several times from two different shelters.
The Humane Society in Portland Oregon is one of the worst places I have adopted a kitten from. They send you home with sick animals that also have worms. They don't tell you the kittens are sick but they are sure to take your money, rush you out the door and tell you that once you leave with the pet they more or less dont care if the animal is or gets sick.
Again, I strongly believe that giving a home to a homeless animal is the best way to go, but I would think twice about adopting from this place and if you do be prepared to take your new pet to a vet and nurse them to good health and treat for worms.
I am going through this right now with a kitten I brought home yesterday, she is really sick.
I wont adopt from this place again!
