Re: Squirrel regurgitating foamy liquid since morning but wants to eat and drink
I concur with StS. Insertion of a tube might be called for, as a last resort. If there is an obstruction, even if you get the tube inserted without creating damage, you might not dislodge the obstruction; in fact, you might further imbed it. FWIW, I'd follow StS's advice before proceeding to a tube. Prayers and best of luck to both of you.
