You shouldn't use a hot water bottle on any animal that is still recovering from aneasthetic. If they were unfomrotable they may not be able to move off of it.
You might need to syringe feed her, did the vets give you anything to syringe feed her with? Castiel was exactly the same after his neuter, I had to syringe him his food and his water.
I started syringe feeding her yesterday lunch time and have carried on every since doing it every 2 hours except over night. She is also on loads of other things.
How long did you have to syringe feed Castiel?
I'm just getting worried now and panicing. She is pooing now and eating bits of hay and dandilion here and there but no nuggets or drinking much. Thanks.
Thanks everyone. The op last night was because she had torn the muscle causing a hernia. The cut is twice as big now however they sent her home with me after the op last night and this morning she has pooed and wee'd and is eating hay. Back there at 10.20 to see where we go from here. fingers crossed.
