Hospitalisation
Cats, dogs, rabbits and small furries have cages to themselves. They can't see other patients and so can't become anxious. The cages are designed for easy maintenance and are thoroughly disinfected between patients.
All cages are big enough for overnight stays should that be necessary, but this is relatively rare as most pets are best off recovering in their own homes.
Overnight in-patients are looked after by the nurses who will attend frequently as neccessary, and will be able to call a vet if needed.
