Exam 4 Flashcards
Why + how do reptiles use escape mechanisms?
Through their behavior, they do this in order to avoid detection
What are some escape mechanisms that reptiles use?
Immobility, olfactory masking, micro-habitat selection
What is aposematic defense behavior?
Using color in order to deter predators
What is ecdysis?
The process of shedding skin
What are some actions that may prompt stress hormones?
Change in habitat features No concealment location Unusual sensory cues Handling Group housing
Is captive enrichment good for reptiles?
No!
Should reptiles be trained?
No!
What type of enrichment should reptiles have?
The only enrichment that a reptile should have is finding live food
What are examples of scent communications seen in the Caressing the Tiger Video? What purpose did they serve?
- Spraying deposits to mark territory
- Scratch marks are visual and glands from paws
- Glands on face and tail –> used to mark territory
How do cats display aggression / avoid fights?
Body posture/intimidation (hissing, growling)
What are the friendly greetings of cats?
more subtle and fleeting - nose touch or body rubbing
How do cats learn to hunt?
In the wild: mother cat will bring live prey for young to learn
- learn to hunt/ stalk through play
What is high-rise syndrome? How do cats correct during a fall?
When cats in large/ tall apartments look out windows and fall out –> cats that fall further are usually hurt less. They have time to free fall and relax so that the impact is not as much
What are common behaviors between domestic cats and big cats? What are behavioral differences?
Most behaviors of domestic cats have a parallel in the wild.
- Cat mothers keep their young clean, refine predatory skill through play
- Always alert for cues that signify food or danger
- Same communal behavior as lion prides in grouped domesticated cats
What are adaptations the cat has made to live in groups?
There is a subtlety to cat communication when living in groups. Cooperative care by groups of females means that young will be more likely to survive.
Why is it that in the cat hunting behaviors are still selected for and in the dog, they are not (resulting in the average domesticated dog being an inefficient hunter)?
Non pedigree cats are not completely domesticated. Feral cats have to rely on their own hunting ability to feed themselves.
~ we domesticated cats with the idea that they would hunt rodents. Dogs don’t need to hunt on their own
–> Not as much selective breeding for cats
What is the monotony effect?
When cats get bored of food if they eat the same thing.
How is the monotony effect beneficial to the survival of cats?
This effect should reduce the probability that an unbalanced diet is taken because no two foods with markedly different flavors should contain the same nutritional deficiencies
What is neophobia?
Fear of new food items + when cats prefer food they’ve had previously
How is neophobia beneficial for the survival of cats?
The possibility of strong contrasts could indicate that the food is not safe to eat
Does nature or nurture have a more pronounced effect on food preferences for cats? Why is this important?
Nurture –> cats will develop taste for what their mother ate and what they are fed when they are young
Why would it be advantageous to feed cats a variety of foods?
Because it would ensure that they are having a variety of nutrients for a complete diet
Where was the cat first domesticated?
Ancient Egypt
Why were cats domesticated?
Domestication due to grain silos
- Abundant amount of grain attracted a large number of rodents
How do the cats’ physical changes differ from that of the dogs due to domestication?
The cat has undergone fewer physical changes due to domestication compared to dogs
What has selective breeding led to in cats?
Selective breeding has led to changes in hair coat and eye color
Is the domesticated cat still very similar to the wild predecessor?
Yes
How many different breeds of cats are there
Over 100 different breeds of cats
- Around 40 recognized by breed associations
What are cat breeds based on?
Body type, coat color and length, and eye color
How much breed variation is there of cats compared to dogs?
Less breed variation
What is cat parenting like?
- Some cats monogamous and co-raise young
- Mostly mother raises young
- Initially, nurse as much as 6-8 hrs/day
- Group cats –> communal rearing
Neonatal cats
- Altricial
- Primary behavioral concerns:
~ Acquire food, stay warm, maternal care - Relatively immobile
- Thermoregulatory systems not fully developed
- Require tactile stimulation for urination and defecation
- Well- developed olfactory and tactile systems
- Poor hearing and eyes closed
Neonatal cats innate behaviors
- Rooting reflex: ~ Triggered by maternal licking ~ Enables kittens to locate teat ~ Develop nipple preference - Go limp while being carried by scruff of neck
Feeding behaviors
First 2 weeks:
- At least 4 hours per day
At 2-3 weeks:
- Decreases to 2-3 hours per day
Mother initiates feeding for first 3 weeks
Mother cat parenting
- At 3 weeks, suckling initiated more by young
- At 5 weeks, mother brings home prey to kittens
~initially dead prey
~as get older, brings live prey
When do kitten eyes open?
Eyes open between d 2 and 16
- Most 7-10 days
What affects when eyes open?
Varies depending on genetics. age of mother, handling by humans, kitten’s gender
When do kittens recognize mother visually vs olfaction?
By 3 weeks
When do ear canals open?
Over first 2 weeks
When do kittens have adult orientation to sounds?
At about 5 weeks
When do deciduous teeth erupt?
At about 2 weeks
- Continues to 5 weeks
When do kittens begin replacing neonatal behaviors with adolescent and adult behaviors
3 weeks
- Don’t need stimulation for elimination
- Will leave sleeping area
- More mobile
When do kittens develop full adult repertoire?
7 weeks
When is kittens most sensitive period?
Between 2 and 7 weeks old
What happens when kittens have no interaction?
They are hard to tame
What is appropriate amount of socialization for kitten per day?
At least 30 min per day
Role of Adult Cats in Behavioral Development
- Strong bond between mother and offspring
- Father not involved in parental care
- May also be impacted by social group if housed in a group
What does mother provide to kitten (food)?
- Nursing
- Between 26 and 32 d, bring killed prey
- Week 5, mother brings live prey
- Beginning of weaning process
~ completed by 8 to 10 weeks of age
How does natural behavior relate to how we should wean kittens?
Start with softened kitten food at about 2-3 week mark to end of 8 week time frame
Kitten learning
Learn by observation - Primarily mother - How to act around humans - How to hunt Learn prey recognition, link between predation and food, prefer food mother is fed

What is hallucinatory play?
When they play with things that aren’t there
Olfactory communication in catd
Used to mark territory
Also conveys cats gender, reproductive status, and identity
If live in a group, produce group-specific odors, identification, and group cohesiveness
Sprayed urine
- More pungent
- Provides reproductive status, territory
- Not a threat or “stay away” signal
Fecal Scents
Glandular secretions added as voided
Bury feces within home or normal territory
Don’t bury when out hunting
- Territorial marker
- May also communicate status of the animal
Submandibular
Below job
Perioral
On sides of mouth
