Onset of symptoms
Obesity
1. Can begin at 1 to 2 years after spay or neuter 2. Often becomes more obvious at 4 to 8 years
Probability Of Onset:
Very high, this is the most common preventable condition in the breed
Hypertrophic cardiomyopathy
1. Can be diagnosed at 1 to 2 years 2. Clinical signs often appear at 5 to 10+ years
Probability Of Onset:
Low to moderate, CFA indicates it largely disappeared from the breed with preventive testing and selective breeding while external text notes some lines may carry a mutation
Dental disease
1. Mild gingivitis may start around 1 year 2. By age 3 many cats have some disease 3. Cornell notes many cats older than 4 years are affected
Probability Of Onset:
Very high, 50 to 90 percent of cats older than four years have some dental disease
Feline lower urinary tract disease
1. Often occurs at 2 to 6 years 2. Can occur at any age
Probability Of Onset:
Moderate. Risk may be higher in overweight indoor male cats and with dry-food-only patterns
Diabetes mellitus
1. Typically middle-aged to older cats 2. Often 8+ years especially with obesity
Probability Of Onset:
Moderate to high with obesity, about 1/100 to 1/500 cats may be diagnosed during life
Reasons
Obesity
1. The text indicates this is caused by excess calories and insufficient activity rather than deficiency
2. Caloric control is the main missing factor in daily life
Dental disease:
1. Plaque and oral bacteria are the main cause
2. Mechanical abrasion and tartar-control additives may be lacking in some routines
Hypertrophic cardiomyopathy
caused by genetic disorder. Also, taurine deficiency is linked to a different cardiomyopathy
Feline lower urinary tract disease
Water intake may be lacking and concentrated urine may increase risk
Diabetes mellitus
this is metabolic dysfunction tied to excess calories and carbohydrates rather than a simple deficiency
Obesity:
- Dietary management with precise calorie control may be the cornerstone
- Portion control , scheduled meals , and increased play and enrichment may be used
Hypertrophic cardiomyopathy deficiency :
- Echocardiography may be used for diagnosis
- Medications may be used to relax the heart muscle , manage lung fluid , and reduce clot risk
- The text indicates there is no cure but management may help for years
Dental disease
- Daily tooth brushing may help prevent disease
- Professional dental cleaning under anesthesia may be needed
- Extractions may be needed for severe periodontitis
Feline lower urinary tract disease:
- Increasing water intake and canned food may help
- Pain relief , prescription urinary diets , and stress reduction may be used
- Urethral blockage is not recommended to manage at home and may require emergency catheter care
Diabetes mellitus:
- Insulin and dietary therapy may be used
- Low-carbohydrate diet , weight management , and blood glucose monitoring may help
- Some cats may enter remission with early management. Ask professional vets for detailed information.
Obesity :
- L-carnitine can,might be helpful for fat metabolism and lean mass support.
- Omega-3 fatty acids EPA,DHA can,might be helpful for joints stressed by excess weight
Hypertrophic cardiomyopathy
- Taurine and L-carnitine can,might be helpful for heart muscle metabolism if a veterinarian recommends them.
- Coenzyme Q10 can,might be helpful for cellular energy support.
- Omega-3 fatty acids EPA,DHA can,might be helpful for inflammation or arrhythmia support
Dental disease
- Seaweed extract Ascophyllum nodosum can,might be helpful for plaque and tartar support.
- Water additives can,might be helpful for plaque control. 3. VOHC-accepted dental treats can,might be helpful for plaque and tartar control
Feline lower urinary tract disease
- Glucosamine and chondroitin can,might be helpful for supporting the bladder lining.
- L-theanine , tryptophan , or milk protein derivatives can,might be helpful when stress support is needed
Diabetes mellitus
- Chromium can,might be helpful for insulin sensitivity support.
- B-vitamins especially methyl-B12 can,might be helpful for nerve support
