Oh no, that wasn't good that Toby ate the blanket! Unfortunately no, there is nothing you can do to help him pass it, it will either pass on it's own or cause a blockage. I am concerned that he isn't eating much, and that can be a sign of an intestinal blockage from the blanket. The best thing to do is have him seen by a vet for x-rays to see if the blanket has caused a blockage or not. If it has, he will need surgery to fix it. I would see if you can borrow money from family and friends to afford the vet, and I can give you some resources that may help you afford a vet. You can see if your vet accepts payment plans, if there is a low cost clinic in your area, or you can apply for Care Credit online. There is also an organization called Red Rover that give grants for treatment of sick animals, and you can see if you qualify for one of their grants. Best Friends also has a list of resources that offer financial assistance on their website.

The Onyx & Breezy Foundation has many programs including helping people with medical bills. They are a good resource for information.
Brown Dog Foundation provides funding to families with a sick pet that would likely respond to treatment, but due to circumstances, there is not enough money immediately available to pay.
IMOM is dedicated to insure that no companion animal has to be euthanized simply because their caretaker is financially challenged.
I hope one of these resources helps you afford a vet! Good luck.
