To understand why let’s talk a little more about kittens and their development.Do British Blue kittens’ eyes change colour? They do. The kitten’s eyes will start out a pale, hazy blue. Gradually, over the course of several weeks, the famous copper shade will start to appear – first around the pupil, then gradually spreading to the rest of the eye. All kittens’ eyes change colour in a similar way, with the exception of cats who will be blue-eyed into adulthood. To the best of my knowledge, there isn’t a cat who starts life with their eyes already showing adult colouration unless their eyes will be blue anyway. If you bought your kitten from a registered breeder, she should already be at least 12 weeks old; by this age, most cats should have their adult eye-colour. If the kitten’s eyes haven’t quite finished changing or if you have a younger kitten for some reason, they may still be partly or wholly blue. When a kitten is born, its eyes will be closed. In fact, the kitten’s eyes haven’t even finished developing. The kitten doesn’t yet have any developed senses beyond touch, smell and taste; not only are their eyes tightly shut and still forming but their ears are still developing too. They can’t hear very well and can’t see at all. The little blind kittens will be completely dependent on their mother initially. Neonates can’t even regulate their own body heat. When they’re first born, these tiny creatures will fit in the palm of your hand.
- For the first week, they will do little more than eat, sleep and grow.
- By the second week, the kittens are a lot bigger and their eyes may have started to open.
- Sometime between 9 and 14 days old, the kitten’s eyes should be fully open.
Why do British Blues have copper eyes?British Blues are a lovely and highly regarded variant of the British Shorthair. They are perhaps the most popular colour for this breed. The ideal British Blue has solid blue-grey fur with no other colours or markings. She has a solid, cobby body, a rounded head and rounded features. Her eyes are large and round, with amber, orange or copper irises. British Blue cats were created in the early days of the breed when British Shorthair cats were deliberately mated with Russian Blue cats in the hopes of creating a variety of the British Shorthair breed with the Russian Blue’s blue-grey coat. These matings were successful in introducing the blue fur trait to the breed. Breeders then had to work to create a true British Shorthair with both the blue colouration and the handsome traits of the original line. These include the coppery eyes of the British Shorthair. Russian Blue cats have eyes that are green, blue-green or sometimes blue in colour, creating a markedly different effect than the copper-on-blue contrast we see in the British Blue’s colouration. The coppery eyes are inherited from the earliest British Shorthairs and are very much sought-after by breeders, cat fanciers and ordinary pet owners alike.
So there’s nothing wrong with my British Blue kitten’s eyes?This is the first question some inexperienced kitten owners ask when the kitten’s eyes open and they see that greyish-blue colour instead of the orange they were expecting. Is there something wrong with the kitten? No. This is entirely normal and really shouldn’t concern you. British Shorthairs, in general, aren’t especially prone to eye issues; their large, round eyes are well-formed and typically very healthy. Like any cat, however, your British Blue can develop eye problems in kittenhood. Kittens are delicate and their immune systems aren’t fully developed yet; this makes them vulnerable to infections. They are also curious, playful and rumbustious, forever getting into scrapes and potentially suffering harm. Even as simple as a misplaced foot by a litter-mate can cause an injury. Signs that your kitten might have issues with her eyes include mucus or other discharge, squinting, bumps or swelling around the eyes or obvious injuries. If you see any of these symptoms in your British Blue kitten, it’s important to have the vet see her as soon as possible. Eye problems can deteriorate quickly and may become very serious if they’re not attended to promptly. In the most extreme cases, a kitten could lose the sight in one or both eyes. Severe infections can even kill your pet. [sc name=”WET FOOD”]
My British Blue kitten is older than 12 weeks but still has blue eyes. Will they ever change?By the time the kitten is three months old, their original eye colour has usually changed completely. While some cats do take longer to fully develop their adult eye colour, you should certainly have seen plenty of changes by 12 weeks of age. If the kitten’s eyes are still solidly blue at this point, without even a ring of colour around the pupil (the dark part of the eye) there’s a good chance they’re not going to change and you simply have a blue-eyed, blue-haired cat. This isn’t unheard of – while British Shorthairs with the British Blue colouration usually have eyes that are described as copper-coloured or amber-orange, they do pop up with blue or green eyes from time to time. Your kitten is fine, just a blue-eyed baby rather than an amber-eyed one. If the cat’s eyes still haven’t changed in another week, they’re definitely staying blue. For myself, I think it’s a rather appealing combination – while I find the typical copper eyes very striking, there’s something charming about the combination of blue eyes and grey-blue fur. Some people immediately suspect that they may not have a pure-bred British Shorthair on their hands – that their kitten may be mix of British Shorthair and another type of cat, such as a Russian Blue or a Ragdoll. This is not necessarily the case. Although it’s a rare eye colour in this breed, there are pure-bred British Shorthairs who have blue eyes; they tend to have white rather than blue fur but again it is still possible.
I love my British Blue’s copper eyes but I liked those blue kitten eyes too. Can I find a cat whose eyes won’t change?You can purchase a British Shorthair kitten or cat with blue eyes – silver or white coloured Shorthairs often have duck-egg or azure irises. If you’re in love with blue-furred cats, the slim Russian Blue is a related shorthair breed with blue fur and blue or green eyes. In fact, there are several wonderful cat breeds who keep their blue eyes permanently. The Siamese is perhaps the most famous but there are other cats with charming blue eyes. The intelligent, mischievous Balinese and hyper-social Tonkinese are two popular ones. (If you opt for a Tonkinese cat, do bear in mind that they need plenty of companionships – you might end up getting two just to keep them occupied). My personal favourite is the Ragdoll – they have baby-blue eyes, long, thick fur and very loving natures, as well as being a lively companion who’ll get on famously with your British Blue. If you do decide to get a blue-eyed cat, do be aware that some breeds are prone to issues such as myopia, nystagmus and a tendency to blindness. This needn’t impact the cat’s well-being – I’ve known plenty of completely sightless cats who were perfectly happy and enjoyed life to the full – but blind or partially sighted cats do need extra care that fully sighted cats don’t. Light eyes tend to go with light fur colours, especially white, and these come with various issues such as a propensity to burn in the sun and develop melanoma. White-furred cats are often deaf in one or both ears as well, which can impact their well-being. [sc name=”CAT LITTER RED”]
Do Russian Blue Kittens’ Eyes Change Color Like British Shorthairs?
Yes, Russian Blue kittens’ eyes change color just like British Shorthairs. Both breeds undergo a gradual transformation in eye color during the early stages of development. They start with blue eyes and gradually transition to their distinctive adult colors, commonly green or gold. This british shorthair and russian blue comparison highlights their shared trait in eye pigmentation.
Are British Shorthair Cats Effective Mousers?
