Kat is right, she knows what she's talkin about, she used to be a vet tech.
I have personally gone through a blockage w/Momo & it involved constant vomiting & diarrhea...he even threw up water, he couldn't hold anything down. He ended up having surgery to remove a queen palm seed which was enlodged in the entrance of his small intestine.
I'm wondering if something was there, but later it passed into the intestines, it's still somewhere in her intestines & causing the vomiting & diarrhea?
That's what happened to Momo, I was sure he ate the palm fruit along w/the seed & we did an xray in the morning. Saw something in his stomach & by the time we went to an emergency specialty vet a few hrs later, it had moved from his stomach, it wasn't in the xray anymore. So I was confused & scared, the vet said he'll try different anti-nausea meds & see if it'll pass. Also did endoscopy & only saw severe ulcers on his stomach lining. They also did colonoscopies & ultrasound & saw nothing. On day 7 (yes, he was there suffering for 7 days
, only thing keeping him alive was the iv) the vet felt the seed when he palpated & did the surgery. It was hell for both of us, never would wish this on anyone. If I had not been so scared, I would've just told them to go open him up the 1st day, bc of my indecisiveness, I let him suffer for a whole week. Just thinking about it breaks my heart again.
I hope your girl will be ok!
