Capacity for Care Calculator

Use this tool to compare today’s animals in care to your usable housing units and available care minutes. The results help you decide whether intake can continue at the current pace or should slow while you recover capacity.

Step 1 – Animals in care

Start with a point in time count of animals physically in the building. Separate animals that need extra daily care time from those whose care is closer to standard.

Cats

Count all cats in adoption, intake, holding, medical, and other housing areas within the facility. Do not include cats in foster care or at offsite partners.

Include cats needing significantly more time, such as neonates, sick or injured cats, or cats on intensive behavior or medical plans.

Dogs

Count all dogs housed onsite, including adoption, intake, holding, and medical areas. Do not include dogs in foster care or at offsite partners.

Include dogs that require extra time for medical treatment, intensive behavior work, or complex feeding and handling needs.

Step 2 – Housing units

Enter the number of usable units for cats and dogs in each area. Only count units that meet welfare standards and are intended for daily housing, not emergency overflow spaces.

Cat housing units

Count units where cats are housed once they are available or nearly ready for adoption, such as adoption rooms or condos.

Count units used for intake, observation, or short term holding, such as admission or isolation rooms that meet size and design standards.

Count units used primarily for medical treatment or infectious disease isolation that are still appropriate for ongoing housing.

Dog housing units

Count kennels or runs where adoption ready dogs are normally housed. Size should be appropriate for the dog’s body size and needs.

Count units where dogs are housed for intake, observation, or short term holding when those units are suitable for ongoing housing.

Count units where dogs receive medical treatment or are isolated for disease control that are still built for daily housing.

Percentage of total units that you plan to keep open as a buffer. Many shelters start with a 10 to 20 percent margin and adjust over time.

Step 3 – Staff and volunteers

Enter the number of staff and volunteers who contribute to daily animal care and estimate what portion of their time is spent on direct care tasks.

Full time staff

Include full time staff whose duties include feeding, cleaning, treatments, and other hands on animal care.

Enter the typical scheduled hours in a shift for full time staff, for example 8 hours.

Estimate the percent of each full time shift spent on direct animal care after subtracting meetings, breaks, administrative tasks, and travel.

Part time staff

Include part time staff whose regular duties involve direct animal care.

Enter the typical scheduled hours in a shift for part time staff.

Estimate what portion of each part time shift is spent on direct animal care tasks.

Volunteers

Include only volunteer hours that occur reliably, such as scheduled kennel cleaning or enrichment shifts. Estimate an average per day.

Estimate what portion of volunteer time is spent on direct animal care tasks as opposed to orientation, training, or other duties.

Foster support work

If staff spend regular time each day on foster coordination, calls, or support, enter those minutes here so the model counts that time against total capacity.

Step 4 – Care minutes per animal

Estimate how many minutes per day are needed to feed, clean, and care for a typical animal, plus extra time for special care animals and basic enrichment. These values can be refined over time as you collect data.

Standard care minutes

Include routine feeding, litter box care, cleaning, and basic health checks for cats without special needs.

Include feeding, cleaning, letting dogs out or walking for basic needs, and basic health checks for dogs without special needs.

Special care minutes

Include additional time for treatments, hand feeding, neonatal care, or behavior support for cats that need extra attention.

Include additional time for treatments, special handling, or behavior and training plans for dogs that need extra attention.

Enrichment

Include planned time for play, social contact, or other enrichment activities per cat per day.

Include planned time for walking, play, training, or other enrichment activities per dog per day.

Care safety margin

Percentage of extra care time to add on top of calculated minutes to account for variation and unexpected needs. Many shelters start with 10 to 25 percent.

Step 5 – Projections and LOS (optional)

Use this step if you want to see how changes in intake and outcomes over a chosen time frame might affect population, and to explore length of stay targets using the magic number relationship.

Population projection

Enter the number of days you want to look ahead. Set to zero if you do not want to use the projection feature.

Projected cats

Include all sources of intake you expect during the projection period, such as owner surrenders, strays, and transfers in.

Include adoptions, transfers out, return to owner, and other live outcomes you expect during the projection period.

Projected dogs

Include all expected dog intakes across the same time frame.

Include adoptions, transfers, return to owner, and other live outcomes you expect for dogs.

Magic number inputs (advanced)

The magic number relationship says that required daily capacity is equal to average daily intake multiplied by ideal length of stay. You can also solve for the length of stay needed to stay within your current capacity.

Average daily intake

Use recent intake data (for example, 3 to 12 months) and divide total cat intake by the number of days to get an average per day.

Use the same time period to calculate an average daily intake for dogs.

Target LOS (optional)

Enter the ideal average length of stay in days for cats. Leave at zero if you want the model to calculate the LOS needed to fit within current capacity.

Enter the ideal average length of stay in days for dogs, or leave at zero to have the model calculate the LOS needed.

Step 6 – Results

Review the summary of housing and staffing status, then use the detailed numbers and the magic number section to discuss options for intake, staffing, and flow.

Projection

Projected cats in care after horizon: 0

Projected dogs in care after horizon: 0

Set a projection horizon and expected intakes and outcomes in Step 5 to see projected population.

Capacity over time (magic number)

Required cat capacity given your intake and target LOS: 0

Required dog capacity given your intake and target LOS: 0

Average LOS needed to stay within current usable cat capacity: 0 days

Average LOS needed to stay within current usable dog capacity: 0 days

Enter average daily intake and target LOS values in Step 5 to use the magic number view, or leave LOS fields at zero to see the LOS needed to stay within capacity.
