Obviously every cat owner wants their cat to be as healthy as possible.
And cats are generally kept healthy by the range of high quality commercial diets which are now available. (We put the emphasis on high quality - there is a lot of low quality available in the market). In addition to diet vaccinations help to prevent major diseases - it is worth checking that all your cat's vaccinations are up to date next time you visit your local vet.
Older cats can be prone to cat health and cat nutrition problems. And these can call for specific cat care.
Cat health: how probiotics help cat nutrition
In addition to obvious infections such as E.coli and Salmonella what can happen in some cats is inappropriate bacteria can overwhelm the gut of stressed, sick or elderly animals and cause diarrhoea. This condition can often be hard for a vet to correctly diagnose. However Probiotics (friendly bacteria) for cats are useful because they help to stabilise your cat's gut while the natural bacteria recover. They are especially useful in supporting elderly cats.
Probiotics help cat nutrition by increasing the guts ability to absorb nutrients from the food travelling through it. They also reduce the odour associated with wind. Some people consider them an essential part of their cat health and cat care, basically because a healthy gut/intestines leads to a much healthier animal.
