Slow disease progression
Alleviate clinical signs of disease
Optimal BCS
Preserve lean tissue mass
64
Explain provision of water in seniors
Clean, fresh and always available
Water fountains, Pyrex dishes (some cats x like smells), shallow bowls (cats x like wet whiskers)
Monitor and report changes
65

Moderate to low levels
Provide E when needed, Palatability, Fat soluble vitamins ADEK, EFAs
66

Need to be good quality and bioavailable (reduces waste products)
Maintaining lean mass
Contributes to palatability (especially cats)
Tissue synthesis
Immune function
*do not restrict unless renal impairment
67
What is the function of carbs in senior nutrition
Less necessary in cats
Provides E (excess stored as fat)
Carbon skeletons for no-essential nutrient synthesis
Protein and fat sparing so they can be used for other processes
Fibre

In urine
72
What should Mg content of senior diets be?
Moderate
If too hi, struviate urinary crystals
If too low, Ca oxalate crystals
73
Name 3 antioxidants
VIT C
VIT E
Selenium
* we don’t know which antioxidants are most useful but unlikely to cause harm so we give them all anyway
74
What is the result of oxidative stress?
Free radical production
Free radicals damage DNA, cells and proteins
Process is accelerated with aging
75
What is obesity?
A CHRONIC INCURABLE DISEASE
76
Why does obesity have lifelong consequences (incurable?)
Metabolic E requirement after weight loss is lower so can’t return to normal diet and must receive continued obesity care as have lower calorific needs
77
Explain fat gain
Adipose tissue is formed from increasing numbers of adipocytes during growth that expand during adulthood
Active endocrine tissue releases hormones called adipokines which are detrimental as may cause inflammation, insulin resistance and impaired immunity
78
What are the implications of obesity?
Osteoarthritis (too much weight on joint plus inflammatory adipokines make pain worse)
Airway disease
Urinary disease (FLUTD)
Metabolic disorders (diabetes)
Increased cancer, surgical, anaesthetic risks
Poor skin and coat due to inability to groom
79
Name 4 alternative diets
Raw Meat based diets (RMBD)
Home-cooked prepared diets (HPCD)
Vegan diets
Grain free diets
80
Why should pets not necessarily be fed like their ancestors?
Domestication and evolution e.g. of the 36 genomic differences between dogs and wolves, 10 are responsible for carbohydrate digestion
Also differences in lifestyle and lifespan
81
What are the claimed benefits of RMBD (no supporting evidence)
Reduced incidence of GI signs
Improves stools (no fillers)
Better breath
Reduced risk of obesity
Reduced shedding
Fewer allergies and skin complaints
Better behaviour
Fewer parasites
Lower veterinary costs
82
What are some of the risks of RMBD?
Dental fractures
Oesophageal obstructions
Gastric FBs
83
Why might palatability of RMBD be better?
Increased fat and moisture (good for picky eaters but x if prone to obesity)
84
What are some common pathogens in raw food (especially issue if bought food from supermarket that was intended to be cooked)
Also remember pathogens are also a risk to the owner and the enviro
Salmonella
Campylobacter
Listeria
E.coli
Staphylococcus
Tuberculosis
Norovirus
85
How to check if food is nutritionally balanced (difficult with raw meat based diets and can have lifelong consequences)
Laboratory analysis and feeding trials to be overseen by a qualified individual
86
What are the claims of HPCD?
More natural
Fewer allergies
Lower incidence of GI signs
Better stool quality
Improved behaviours
No carbs (but dogs and cats can generally digest these)
Unprocessed
No additives or preservatives
87
How can HPCD be good?
Food-elimination trials
Better control
Management of proven adverse reactions to food or specific diseases when commercially x available
Improved safety compared to RMBD
Improved palatability (hi fat?)
88
Why is nutritional imbalance such a big risk in HPCD?
VAST majority of diets found to be inadequate
89
What are the downsides of HPCD?
Unaffordable (formulation costs, ingredients, supplements)
Not easy
Time
Viable long-term option?
90
Can dogs eat a vegan diet?
Dogs are more omnivorous than carnivorous and are genetically different from wolves
They have a greater capacity for utilising carbs
Plant diets can be formulated to be complete and balanced
Studies show that dogs can sustain exercise on vegan diets
91
Can cats have a vegan diet?
NO
Cats are obligate carnivores - they need animal products to gain Taurine and arachidonic acid or will have a nutritional imbalance
Taurine is the most common limiting aa, synthetic sources may not be bioavailable
Arachidonic acid has no synthetic alternatives
*egg sometimes used to balance vegan cat diets
92
What makes grain-free diets a bit pointless
They exclude all types of gluten even though animal is usually on,y intolerant to some of them (blanket approach may cause problems)
* x exclude carbs as can still contain potatoes
93
What is the benefit use of a grain free diet?
Can be used for elimination food trials
However most common dietary reactions are from beef, dairy and soya (not gluten)
94
What is another benefit of grain-free diets?
Can manage skin disease in dogs with proven adverse reactions to foods
95
What condition is grain-feee diets necessary for?
Paroxysmal gluten-sensitive dyskinesia (neurological disorder that causes abnormal limb movement)
96
What condition is concerningly associated with grain in dogs
DCM
97
What is DCM?
Dilated cardio myopathy
May or may not be related to grain-free diets?
