Symptoms that cats present

It is easier than we think to check if our pet has cataracts. The main symptom is the appearance of a bluish gray spot in the cat's pupil. That spot can be of various sizes and the larger it gets the more the waterfall is advancing. Sometimes the cataracts evolve rapidly and end up covering the entire pupil, making it impossible to see the cat. In addition, they can develop in both eyes or even may be present from the birth of the cat, being considered congenital.

In addition to this clear symptom, others can be appreciated if we look closely at our pet:

  1. Difficulty at the time of recognize people of its surroundings
  2. Steps abnormally high
  3. Wandering abnormal
  4. Change in shape and size of the pupil
  5. Runny nose Derived from the eye. This is because the cataract has been formed by an infection.
  6. Insecurity when walking
  7. Clumsiness when moving around their usual environment
  8. Miscalculate the distances
  9. His eyes turn very wet and can change color


Just detect any of the symptoms mentioned above is necessary take our pet to the vet with the maximum possible speed, since the sight of the cat is at stake. A timely diagnosis is crucial to remedy the primary symptoms and stop the progression of the cataract.

The veterinarian will check both eyes of the pet and verify that it is obviously a cataract. For it similar devices are often used to those found in an ophthalmologist's office, to check the different structures of the eye and the seriousness of the matter. In addition, on many occasions the veterinarian will perform an ultrasound of the animal to check for tumors, hemorrhages or retinal detachments. Once the procedure is finished, the causes of the cataract and the best treatment for our pet will be known.

In the case of adult cats the treatment may vary depending on the state of the cataract. Which they have a slight opacity and do not alter the cat's vision They do not necessarily need treatment, unless it continues to get worse over time. On the other hand, cataracts that affect baby pups can improve on their own, without the need to provide a treatment.

Within the existing treatments we find the anti-inflammatory eye drops, which help eliminate the possible infection causing cataracts and relieves feline symptoms. This medicine is Recommended for cats that do not have a highly developed cataract and should not necessarily be operated. Next to the eye drops will be recommended feed the cat in a balanced way and add vitamins to your diet, since nutritional deficiencies are a factor that can make cataracts worse.

The other option to treat our pet is undergo surgery. This treatment is carried out when felines show severe vision impairment. The operation consists of make a small incision in the cornea and, using high precision instruments, absorb the cataract thanks to the use of ultrasound. After this the lens is replaced by an artificial one that will allow the cat to see both near and far clearly. The forecast of the operation will be more favorable for the cat if it is done as soon as possible.

After surgery the pet should not be admitted to the veterinary center. An Elizabethan collar will be placed to avoid touching the eye and harming or causing an infection. In addition, the veterinarian will prescribe the necessary medication for pain, swelling and dilation. By last, several revisions must be made to check the evolution of the cat and the effectiveness of the operation.

The problem with this type of surgery is its high price, which leads many owners not to subject their cat to intervention. In the event that the owner decides not to submit his pet to the surgical intervention, he must submit it to continuous veterinary reviews to monitor the progress of your cataract.

What happens if we do not subject our cat to treatment?

It is known that cats do not have a good view, being the smell their most developed sense. Therefore, a small waterfall that does not advance in time would not make life difficult for the cat. As a recommendation, a cat with a partial or total loss of vision must be kept inside the house to ensure your well-being and security.

The consequence of not subjecting our pet to surgical intervention is varied. The cat can go completely blind or simply lose some sharpness if the cataracts don't get worse. The development of cataracts until vision loss can end by cause great pain to the pet, caused by a state of hypermaturity of the cataract. This involves the entry of small particles in the lens that cause a dangerous inflammation called phacolytic uveitis. The inflammation will cause the lens to acquire a larger size, which will end up becoming a glaucoma or ocular hypertension, and the only solution reached at that point will be surgically remove the affected cat's eye to avoid unnecessary pain.
