It is quite common for older cats to develop problems with their kidneys.
Unlike cells in other parts of the body when kidney cells stop functioning they cannot be replaced. As your cat grows older it is inevitable that his kidneys will not function as efficiently as they did in the past.
Cats are carnivorous animals that are adapted to a diet rich in proteins.
Proteins are broken down by the body into smaller units called amino acids. There are twenty of these. They are used to replace damaged cells, allow growth and facilitate bodily functions. Amino acids from the diet that are not needed by the body are converted into urea that is excreted by the kidneys.
When the kidneys are damaged they are no longer able to remove all of these waste products and toxins from the blood. The urine cannot be concentrated properly and too much fluid is lost from the body. We can do a simple blood test to access the degree of damage to the kidneys and decide the best course of treatment.
Often the most useful way that we can help your cat to cope with his disability is to feed a diet that is low in protein and phosphorus. The right kind of proteins in restricted amounts will greatly reduce the work that the kidneys have to do so that urea levels in the blood stream will remain under control. When the kidneys are unable to maintain low phosphorus levels in the blood biochemical changes occur in the renal tubules that result in further destruction of the gland.
Cats with Chronic Renal Failure tend to have poor appetites and will lose weight. Sometimes it is helpful to warm the food a little to make it more tempting. Always ensure a supply of clean water is available, serious damage will occur if your cat is left without water. We like to weigh cats that are having problems with their kidneys regularly so that we can monitor the progress that they are making.
Another approach we use is to improve the mechanisms by which proteins are used within the body so that there are fewer waste amino acids to be converted to urea and excreted. Anabolic steroid injections have been used for a number of years to do this and have not been shown to have adverse side effects when given to our feline patients with renal problems. The drug is injected every four to six weeks, usually with a vitamin B 12 injection to further improve the appetite.
Some cats are presented with a more advanced form of renal failure. We are able to administer fluid therapy when the disease has progressed to give very high blood urea levels and anabolic steroid injections may help to improve the metabolism of your companion and increase his appetite. Sadly sometimes it is difficult to maintain the quality of his life and a decision has to be made as to whether euthanasia would be a better option.
Feline Dental Care.
Cats are particularly prone to gum infection, (gingivitis), which can develop in patients as young as 6 months old. It is virtually impossible to brush a cat's teeth on a daily basis, so you should always budget for a minimum annual dental descale, (at the time of vaccination booster).
Under anaesthesia, we use an ultrasound machine to remove all the food debris and associated tartar from the teeth, followed by a course of antibiotics. Occasionally, even with this annual treatment regime, it still becomes necessary to extract infected teeth on a progressive basis over the years.
Please do not worry how the cat will eat after multiple extractions. We have a number of patients that have had most of their teeth extracted because of persistent root infections that had not responded to long courses of antibiotics. After the extractions, these patients have invariably thrived and have eaten better than ever !!
You may rest assured that I will advise you if and when extractions are necessary and the number required. Those clients who have acted promptly on such advice have always been very happy that they did so, as their cats have always been much better afterwards.
Prompt and thorough dental surgery produces lifelong health and comfort benefits for your cat.
