Species
Time of day/ year
Physiological state (egg laying, shedding etc. )
Heath status

27
Q

A

Hot spots”
Basking species e.g. beardies
• Need protective guard to prevent burns

28

A

Full spectrum light (UV A, UV B and visible light)

32
Q

What is important to remember about lighting

A

Should be changed every 6 months
Should have daytime and nighttime variation
Should be correct distance from animal —> causes skin tumours amd UV damage

33

A

Non irritant, non toxic
Easy to clean, obtain and replace
Suitable for species, may dig and forage
Provides enrichment

34
Q

A

Hygrometer

37
Q

What are the problems if humidity is too high/ low

A

Too high —> fungal and bacterial dermatitis
Too low —>dyseccyodysis (problems shedding) renal failure

38
Q

How is ventilation important for reptiles?

A

Air changes, not just movement
Prevents pathogen build up and odours
Active —> fans
Passive —> ventilation holes

39
Q

What should carnivorous species be fed?

A

Whole prey (not just muscle)

40
Q

What should omnivorous reptiles eat?

A

Leafy weeds and vegetables
Chopped finely, to avoid selective feeding

41
Q

What foods should reptiles avoid?

A

High oxaloacte foods (reducing Ca availability)- parsley and spinach
Brassicas (can cause thyroid problems)
High phytate containing foods (reduces Ca:P ratio)
Pellets (too high energy and protein)

42
Q

How can feeding snakes alter behaviour?

A

Feed more to calm over active snake down

43
Q

What supplements can be given?

Calcium —> gutting (given to insects before feeding) or dusting
Multivitamins including vitamin D

44
Q

What is brumination and why is it done?

A

Reptile hibernation
For natural behaviour, weight management and breeding
Triggered by drop in temperature
However, need to be careful as uses fat reserves, so BCS must be high enough
