The Ojos Azules coat is largely unremarkable except for one crucial detail: it can be any color or pattern, and regardless of the coat color, the cat will have deep blue eyes. This unusual combination—blue eyes with non-pointed coat colors—is what defines the breed and what made it so interesting to the cat fancy when it was first discovered. Understanding the coat characteristics and grooming needs provides insight into what made this breed unique while also revealing why, apart from the eye color, these were essentially typical domestic cats.
The coat comes in two primary lengths: short and medium (semi-long). Short-coated Ojos Azules have a coat that lies close to the body, typically 1-1.5 inches in length, with a soft texture and moderate density. The coat has normal guard hairs and undercoat, providing adequate protection while remaining easy to maintain. Medium-coated individuals have longer fur, typically 2-3 inches, with more pronounced undercoat and fluffiness, particularly around the neck (forming a modest ruff), on the tail, and on the hindquarters (breeches). Both coat types were described as having normal feline coat texture without any unusual qualities.
The revolutionary aspect of the Ojos Azules was that the coat could be literally any color or pattern (with the exception of pointed patterns, which were excluded from the standard to maintain the breed's distinctiveness). Solid colors including black, blue, red, cream, white, and variations were all acceptable. All tabby patterns—classic (swirled), mackerel (striped), spotted, and ticked—could appear. Tortoiseshell patterns combining red and black (or their dilutes) occurred in females. Bi-colors combining white with any other color were acceptable. Essentially, the entire range of feline coat colors and patterns could appear in Ojos Azules cats.
What made this remarkable is that typically, blue-eyed cats fall into specific categories: pointed cats (Siamese and related breeds) where temperature-sensitive genes restrict color to the extremities; white or high-white cats where genes affecting coat color also affect eye pigmentation; or specific breeds like Ragdolls where blue eyes are breed-specific. The Ojos Azules mutation produced blue eyes independently of these mechanisms, meaning you could theoretically have a solid black cat, a brown tabby, a red tabby, or a tortoiseshell—all with striking deep blue eyes that would never occur naturally in those color patterns.
Some Ojos Azules cats showed small amounts of white spotting, most notably white tail tips, which appeared in some individuals as what seemed to be a linked trait. The genetic basis for this association was never fully understood. However, the breed standard specified that white markings should be limited to avoid confusion with high-white cats who naturally have blue eyes through a different genetic mechanism.
Grooming requirements would depend primarily on coat length and would be typical of domestic cats. Short-coated Ojos Azules would need weekly brushing with a soft bristle brush or grooming mitt to remove loose hair and distribute skin oils. This minimal grooming would be sufficient to keep the coat healthy and reduce shedding around the home. During spring and fall shedding seasons, increasing brushing frequency to two to three times weekly would help manage increased hair loss.
Medium-coated Ojos Azules would require brushing at least two to three times per week, with daily brushing recommended during seasonal shedding periods. A metal comb would help work through any tangles, particularly in areas prone to matting: behind the ears, under the front legs, and in the breeches. The coat texture was not described as particularly prone to matting, suggesting that with regular maintenance, coat care would be manageable.
Bathing would rarely be necessary for either coat type, as cats generally keep themselves clean through grooming. If bathing became necessary due to the cat getting into something messy, a gentle cat shampoo and thorough rinsing would be appropriate. Most cats tolerate bathing poorly, so it should be avoided unless necessary.
Regular nail trimming every two to three weeks would prevent overgrown claws. Ear cleaning would be needed as necessary, typically every few weeks depending on individual wax production. Dental care through regular tooth brushing several times per week would help prevent periodontal disease. These routine grooming tasks would be identical to those for any domestic cat.
The eyes, being the breed's defining feature, would warrant regular monitoring to ensure they remained healthy and clear. Any changes in eye appearance, discharge, cloudiness, or signs of discomfort would require immediate veterinary attention. However, there were no reports during the breed's brief existence of particular eye health issues in heterozygous Ojos Azules cats.
In summary, aside from the extraordinary eye color, the Ojos Azules coat and grooming needs were entirely typical of domestic cats. The breed's distinction lay not in coat quality, texture, or grooming requirements, but solely in the presence of blue eyes in cats whose coat colors and patterns would never naturally be associated with blue eyes. This combination of the remarkable (blue eyes) with the ordinary (everything else) was precisely what made the breed interesting while also highlighting that the mutation affected only eye pigmentation without altering other physical characteristics.
