When You Should Consult a Vet

Although every feline illness isn't life threatening, there are definitely times when a vet's expertise is required. How can you tell the difference? Call your vet anytime you are worried or if your cat is:

Unresponsive
Ill more than 24-36 hours
Having symptoms that dramatically increase or multiply
In obvious pain
Struggling to breathe
Bleeding profusely
Unable to have bowel movements or urinate
Refusing to eat for more than 48 hours
Not drinking

Generally speaking, use your own common sense and intimate knowledge of your cat's normal behavior to guide you. If your intuition is telling you it's time to head to the clinic, do so without hesitation.

Researching Wisely

The importance of a veterinary examination cannot be stressed enough when your cat begins to exhibit signs of disease. Many of the aforementioned cat illnesses share symptoms and a thorough examination is necessary to rule out underlying causes. Something as simple as dehydration may be the secondary effect of underlying kidney disease. Moreover, parasitic infections can mimic the symptoms of inflammatory bowel diseases, though the treatments differ dramatically. An imprecise diagnosis can have highly detrimental results when applied in the place of a medical assessment. A proper diagnosis is the first step towards the safe and accurate treatment of any disease.
