Cat intelligence the average human. Within the encephalization quotient proposed by Jerison in 1973, values above 1 are classified big brained, while values lower than 1 are small brained. The domestic cat is attributed a value of between 1–1.71 relative to human value that is 7.44–7.8. The largest brains in the Felidae family are those of the tigers in Java and Bali, of which the largest relative brain size within the "panthera" is the "tigris". It is debated whether there exists a causal relationship between brain size and intelligence in vertebrates. Correlations have been shown between these factors in a number of
Cadherin related family member 3 infection, which resemble early asthma exacerbations as a phenotype. However, childhood bronchiolitis not caused by RSV infection, of which rhinovirus is often implicated, was associated with the CDHR3 gene variation. This is line with the results from a study on chronic rhinosinusitis, which often is associated rhinovirus infection, where "CDHR3" gene variation also was found to be a strong risk factor. Therefore, CDHR3 seems to causally linked to increased propensity for rhinovirus C infection. Cadherin related family member 3 Cadherin related family member 3 (CDHR3), also known as CDH28 or its abbreviation CDHR3, is a protein that in humans is
