Snowshoe cat very vocal, though their voices are not as loud as the Siamese, a cat found in their breed heritage. They are noted as being very intelligent and have the ability to learn tricks and open doors. These cats also enjoy water, and may swim. In the 1960s, a cat, owned by Siamese cat breeder Dorothy Hinds-Daugherty, produced a litter of Siamese kittens in Philadelphia, Pennsylvania. Three of the kittens had unique markings, consisting of white points and feet. Intrigued by their looks, she began working to breed cats like them, using seal point Siamese with bicolor American Shorthairs. The offspring
Flash point liquid, and equilibrial, such as Small Scale (commonly known as Setaflash), where the vapours are deemed to be in temperature equilibrium with the liquid. In both these types, the cups are sealed with a lid through which the ignition source can be introduced. Closed cup testers normally give lower values for the flash point than open cup (typically lower) and are a better approximation to the temperature at which the vapour pressure reaches the lower flammable limit. The flash point is an empirical measurement rather than a fundamental physical parameter. The measured value will vary with equipment and test protocol
