thanks again for all the advice coming through.
Jax had another bad bout of poo this morning...pretty runny and he strained quite a big but seems in much better spirits since the pain relief has worn off!
we ended up buying a syringe from the chemist last night and force feeding him some re-hydration solution. he's managed to take a couple ice blocks this morning and even did two really good pees (so funny how happy things like this make me!!)
so hopefully he's on the mend. my OH is home with him today and will make sure he has more liquid in him.
funny thing - i tried the vegemite water last night and he refused to touch it, but when i just put vegemite on my finger he licked it right off! must be some bad associations with drinking at the moment?
