Also known as: '''''FIP'''
==Description==
==Introduction==
A progressive disease of the cat caused by feline [[Coronaviridae|coronavirus]]. FIP arises from a mutation of '''Feline Enteric Coronavirus (FECoV)''' in 5-10% of chronically infected cats and not directly from cat to cat. Two forms of the disease exist the '''wet''' or '''exudative form''' and the '''dry''' or '''non exudative form'''.

==History and Clinical signs==
FECoV may cause mild respiratory symptoms and diarrhoea but is often asymptomatic.

Signs of FIP include, chronic weight loss, anorexia, pyrexia, depression, fever and [[Vasculitis|vasculitis]].

==Diagnosis==
'''Dry form'''
'''Dry form'''
Larger, grey granulomatous masses causing thickening of the wall of the [[Small Intestine Overview - Anatomy & Physiology|small]] and [[Large Intestine - Anatomy & Physiology|large intestine]].
Larger, grey granulomatous masses are found in abdominal organs, including the [[Small Intestine Overview - Anatomy & Physiology|small]] and [[Large Intestine - Anatomy & Physiology|large intestine]], kidneys, liver and mesenteric lymph nodes. CNS and ocular involvement occurs in up to 60% of cases, with granulomas causing the clinical signs.
====Histological====
====Histological====
Multifocal pyogranulomas on serosa and throughout gut wall. Infiltration by mononuclear cells, [[Lymphocytes - Introduction|lymphocytes]], plasma cells, [[Macrophages| macrophages]] and a few[[Neutrophils|neutrophils]]. [[Necrosis - Pathology|Necrosis]] and vasculitis will also be seen.

Antibody tests are available to certify FECoV-free cat houses.
Antibody tests are available to certify FECoV-free cat houses.
Recommendations for control and prevention include:
:keeping cats in small stable groups
:good litter tray hygiene to prevent faeco-oral transmission
:reducing stress and minimising concurrent diseases
:avoid breeding from cats that previously produced kittens that succumbed to FIP.
Eliminating FIP from a cattery that has had a case is difficult, but involves closing the cattery to new arrivals and restricting movement within the buildlings. Attempts to produce FCoV-free kittens from an FCoV positive queen can be made through isolation of the queen and kittens combined with early weaning of the kittens at 5-6 weeks of age. But there is a high risk that poorly socialised kittens are produced.
Even once the cattery is free from FCoV, the long-term maintenance of this is any multicat household is extremely difficult.
==Prognosis==
==Prognosis==
Very poor.
