with snuffles it can take a good few weeks to really clear the infection. If shes suffering with snotty nose u can steam her to help clear it out.

I think the best thing for her is to be spoiled rotten without upsetting her tummy, so loads of her fave food and keep syringing her with recovery food (I think you can add a bit of fresh pineapple juice to it instead of water to make them like it more). Keep her warm but defiantly dont put the heating on in the room shes in or this can really mess with them, give her plenty of space to exercise as this really helps their tummys, keep all the new and loud noises to a minimum, and leave her to rest if shes not appreciating your company.

her mouth is probably very uncomfortable at the min, so get as much anitinflammatory pain meds in her as your vet will allow and plenty of metcam too.
