Devon Rex vs Russian Blue
Quick answer
These two breeds differ most clearly in one recorded way, set out below. Neither is better. FaunaHub compares what the registries publish and does not pick a winner — which cat suits a household depends on the individual animal and on circumstances no registry records.
Key differences
- Russian Blue carries the higher published weight figure (4.5 kg against 4.1 kg for the Devon Rex).

Trait rows are three-level bands normalised from a registry's published scale, never scores. “Trainability” describes how readily a breed is said to respond to structured training, not intelligence. “Shedding” is not an allergy signal — no breed is hypoallergenic. A blank means the registry records nothing, which is not the same as the two breeds matching.
Why these two breeds
Both breeds are recognised in the same FIFe category and recorded with the same coat length, which is why FaunaHub compares them. Neither CFA nor FIFe publishes a related-breeds list, so this is a weaker basis than the dog comparisons and the corpus is correspondingly smaller.
