-Feline scabies is a rare but very contagious disease caused by [[Notoedres|''Notoedres cati'']], a burrowing mite. It has not been reported in the UK as of yet. Canine scabies mite, ''[[Sarcoptes scabiei]]'' var. ''canis'' infection can occur in the cat, but is rare and thought to occur mainly when the animal is immunosuppressed. Cases should be screened for [[FeLV]] and [[FIV]] infection and other serious internal disease if this mite is found on them. Affected animals develop [[Sarcoptic Mange#Clinical Signs|similar signs to those in the dog]] i.e. crusting and scale associated with local alopecia, but may not be significantly pruritic.

 The burrowing of female mites meads to damage of keratinocytes and leads to cytokine release.
