Javanese cats are svelte oriental-type longhair felines developed in North America. They have a long, silky coat, deep blue eyes and regarded as good mouse catchers. These cats desire constant attention, so owners would be well advised to keep them busy with toys or another Javanese cat in case human interaction has to wait a while. Baths are rarely necessary. However, combing should be done once or twice a week with a stainless steel comb. Javanese should be kept indoors to prevent them from contracting diseases from other cats. Although they are generally healthy cats, genetic defects and ailments such as cross-eye, deafness, early-onset arthritis, joint issues and hip displacement are possible. The cost for a Javanese cat ranges from $900 to $1,200.
