Indoor Cat Vs. Outdoor Cat

• Outdoor cats generally produce less urine than indoor catscat image by Krzysztof Kiercul from Fotolia.com
  
  Outdoor cats that are able to come and go as they please are likely to produce less urine than those who stay indoors. Cats who are allowed to roam are known for staying gone for days, or sometimes weeks at a time. These cats are unlikely to consume the average or recommended amounts of fresh clean water and wet foods. Hence, they produce less urine than the indoor cat. Indoor cats, on the other hand, have easy access to fresh clean water and wet foods at any time, so they will tend to produce more fluids and urinate much more frequently.
  
  

Older Cat

• Older cats urinate frequently due to weakened bladderscat image by Annika from Fotolia.com
  
  Similar to older humans, when felines begin the aging process, internal organs become weaker and begin functioning at a slower pace. It is common for cats in the elderly stages of life to experience weakening of the bladder and the inability to hold urine for long periods of time. Because of this, the aging animal is forced to urinate more frequently. Although it may seem that the cat is producing excessive amounts of urine, he may actually be producing the usual fluid amount but relieving himself more often. Frequent and excessive urination can also be a disease in older cats. A veterinary examination is recommended to establish an accurate diagnosis.
  
  

Feline Diabetes

  Unquenchable thirst and excessive urination are two signs of feline diabetes, particularly in older cats. If you have an older cat that drinks an excessive amount of water and urinates a lot, keep a close watch for these additional symptoms: weight loss (despite a good appetite), lethargy, poor body condition, poor hair coat or weakness. A combination of these symptoms can mean that the cat is suffering from feline diabetes and may need regular insulin injections and veterinary care. This affliction is most common in cats over nine years old and affects every breed. Cats who suffer from obesity are also at greater risk.
  
  

Urinary Tract Problems

  The most common urinary tract problem in cats is cystitis. Cystitis generally occurs in male cats, and if not immediately tended to can be lethal. Tiny crystals form in the cat's urinary tract eventually causing a blockage. Once the blockage has occurred, the bladder becomes overfilled with urine (and sometimes blood), causing sudden and uncontrollable bursts of the fluids to emerge involuntarily. It may seem that the cat is urinating excessively, but in reality he is just not able to control when or where the urine is released. If the cat does not release the toxic fluids, its bladder can rupture causing the fluids to poison him. This is an extremely serious condition and, if not immediately treated, will cause a certain and painful death for the cat in as little as 24 hours.
  
  

Chronic Renal Failure - Kidney Disease

  Kidney disease, also known as Chronic Renal Failure (CRF), is a potentially deadly condition that can affect cats of any age, but commonly affects older cats as the prevalence increases with age. Chronic renal failure is known to affect felines of any breed, but is thought to be more common in the Persian and Abyssinian breeds of cats, and cats who have experienced prior conditions such as feline leukemia, cancer or immune system abnormalities. In addition to excessive drinking and urination, symptoms to watch for in feline kidney disease are lethargy or fatigue, weight loss, vomiting, halitosis, lack of coordination, weakness and loss of appetite.
  
  

Behavioral Disorders

  If a young cat with no sign of disease is still urinating excessively, especially outside of its litter box, the cat may have a behavioral disorder. Many cats suffer from chemical imbalances in the brain, or have experienced abuse that has caused them mental anguish. This can lead to behavioral disorders, including urinating outside of the litter box. A proper veterinary examination will help you to determine what the cause is for your pet's excessive urination problems.
