Some common assumptions on which sheltering programs are based

Spay/neuter and educational efforts targeted at owners and pets will reduce shelter intake

Animals admitted to the shelter have owners who might come looking for them

Animals admitted to the shelter could be adopted if not reclaimed

Extent of application to cats will vary by community

Why?

Page 15: Paradigm Shift in Cat Management in the Shelter & …...Paradigm Shift in Cat Management in the Shelter & Community Cynthia Karsten, DVM Koret Shelter Medicine Program University of

What are the goals of a shelter?

Abide by all relevant laws Resolve citizen complaints and concerns Reunite lost pets with owners Maintain health and welfare in shelter Find new homes for pets Euthanize suffering or dangerous animals Mitigate harm associated with free-roaming animals Reduce pet over-population

Page 16: Paradigm Shift in Cat Management in the Shelter & …...Paradigm Shift in Cat Management in the Shelter & Community Cynthia Karsten, DVM Koret Shelter Medicine Program University of

Abide by relevant laws? California F and A 31105. The board of supervisors shall provide for both of the following: (a) The taking up and impounding of all dogswhich are found running at large in violation of any provision of this division. (b) The killing in some humane manner or other disposition of any dogwhich is impounded.

Resolve complaints?

Reunite cats with owners? Only ~ 2% of cats

reclaimed by owners nationally 12

Cats are > 13 x more likely to return home by non-shelter than by shelter means 13

66% of lost cats found because they return home

Only 7% found via call or visit to shelter

Find new homes? Less disparity with dogs than

for reclaim and euthanasia Adoption numbers increasing

in many communities Flatter trend

Increasing intake result in increasing euthanasia in many regions despite adoption efforts

< 1% of > 100,000 cats at TNR clinics euthanized for humane reasons8

< 10 % of cats entering shelters are sick/injured15

Median body condition score “ideal”17

Mitigate harm associated with free-roaming animals?

Risk for some diseases is higher in ferals than pets And vice versa

Many conditions also carried by other species

How could we protect public health if killing cats was not an option?

Mitigate harm associated with free-roaming animals?

Studies show mixed effect of cats22,23, 24

Micro-habitat specific effect How could we protect wildlife

if killing cats was not an option?

Page 36: Paradigm Shift in Cat Management in the Shelter & …...Paradigm Shift in Cat Management in the Shelter & Community Cynthia Karsten, DVM Koret Shelter Medicine Program University of

Reality check Most shelter intake is

concern/complaint driven rather than targeted

Capture, transport, holding, lethal injection and disposal is time consuming and costly

Scope is insufficient to reduce overall population

50% permanent removal OR

75% sterilization/release required to reduce population9,10

o Less than 5% of outdoor cat population admitted to CA shelters annually3

o << 1% in shelters on any given day

Rough estimate of 1 un-owned cat per 6 people7; 1 pet cat per 4.1 people

The bottom line: traditional sheltering is not an effective tool to eliminate or protect community cat populations

+ =

Using a tool that’s mismatched to the job is hurting cats, shelters, and communities, and distracting us from finding

real solutions

How about we just stop?

Page 50: Paradigm Shift in Cat Management in the Shelter & …...Paradigm Shift in Cat Management in the Shelter & Community Cynthia Karsten, DVM Koret Shelter Medicine Program University of

What could we do instead?

Expand the options for live release

Limit intake to:o Cats that can be released aliveo Cats for whom death is clearly

the best alternative Invest resources not spent

on killing cats on programs to benefit:o Catso Wildlife o Communities

be euthanasia of that cat or another cato Shelter capacity (including for
