Re: Feline Hip Dysplasia Testing

I would say the numbers of pedigree cats studied are too small to be statistically significant akthough the incidence in Persians/Himalayans (the same breed in effect) seems rather high (and they are a larger breed)


Interesting anyway.




quote=dharma66;1132408]HIP DYSPLASIA: A FELINE POPULATION STUDY by G.G.KELLER DVM,MS, A.L.REED D, VM,MS, J.C.LATTIMER DVM,MS, E.A.CORLEY DVM,PHD, published in Veterinary Radiology & Ultrasound, Vol 40, No. 4, 1999, p p 460-464 gives the following incidences of FHD by breed:

696 cats were studied. The following shows how many of each breed were were found to have FHD over how many of that breed were studied. (for example, of domestics, 35 from 603 werefound to have FHD).

Domestic: 35/603
Abyssinian 0/2
Balinese 0/1
Birman 0/3
Burmese 0/5
Havana 0/1
Himalayan 4/16
Japanese Bobtail 0/1
Manx 0/3
Persian 3/19
Russian Blue 1/2
Siamese 2/28


IMPORTANT NOTE. This is a study of animals that were inspected. Reading those results should not cause alarm. Fro example, you might look at the table and think 'Oh no! Half of Russian Blues have FHD!" The truth is, that is very, very unlikely to be the case. What happened was that two cats of the that breed were examined, and one had it. It may well be that another hundred could be examined, and none of hem have it!

What can be taken from this is that it is definitely not restricted to large cats only. Even a couple of Siamese were found to have the condition.

Another point f interest is tat out of the 81 pedigree cats examined, 12.3% were found to have dysplastic tissue (i.e. to have FHD), whereas 5.8% of domestic cats were affected.

Of the 81 pedigree cats, 40 were male, and 41 female, only 2 males were affected, whereas 8 females were.

This study was of cats presented to the University of Missouri-Columbia Veterinary Medical Teaching Hospital from January 1 1991, through December 31 1995.[/quote]
