Can you call the vet first thing in the morning and ask them for metronidazole, enrofloxacin, an 18 french rubber catheter, and a 60 ml catheter-tipped syringe?
Are you sure? The poop picture that you posted is a cecal poop, and they only produce cecal poops a few times a day. Can you post pictures of what her poop looks like now?
If mine were pooping that, I would treat for cecal worms, blackhead, & E.coli. I would also start tube feeding.
E.coli - enrofloxacin at 15mg/kg twice a day for 3-5 days
Blackhead - metronidazole at 50 mg/kg once a day for five days
Cecal worms - fenbendazole at 50 mg/kg once. Repeat in 10 days...
