Software for small, volunteer-run rescues with no shelter building
Updated · 6 min read · By the Second Tail team

A small, foster-based rescue run by volunteers needs four things: one record per animal, a way to see which foster homes are open, an easy way for fosters to send updates and requests, and a simple adoption process. It can skip kennel management, intake queues and complex reporting. Free tools work until several volunteers share the work; after that, pick software your fosters will actually use, priced in a way that grows with homes, not animals.

What you actually need
- One record per animal with its photos, medical history and documents, that follows it from home to home and into adoption.
- Which homes are open. When a call comes in about an animal, you need to know in a minute who can take it.
- Updates without chasing. A simple way for fosters to send a photo and a line, ask for supplies and ask questions. See how to coordinate foster homes.
- Adoptions. An application, a contract and a way to take the fee. See taking adoption fees online.
What you can skip
- Kennel and run management, if you have no building.
- Intake queues built for hundreds of animals a month.
- Complex reporting nobody on your team will read.
- Anything that needs a volunteer to administer it every week.
When free tools stop being free
Spreadsheets and group chats cost nothing until several volunteers share the work. Then the cost shows up as time: re-asking fosters for photos, scrolling the chat for a vet appointment, retyping updates into the sheet, and the one person who knows where everything is becoming the bottleneck. If that person is burning out, the tool is already expensive.
Questions to ask before you choose
- Will our fosters use it on their phones without training?
- How is it priced, and what will it cost when we're twice as big?
- Can volunteers set it up in an evening, without an IT person?
- Can we try it with a few real fosters first?
- Can we get our data out if we leave?

Where Second Tail fits
Second Tail was built by a foster parent for foster-based rescues. Fosters get a free app on their phone for updates with photos, supply requests and messages, with nothing to download from an app store. The team gets one home page that shows what needs attention, a record for every animal, health schedules, signed foster and adoption agreements, and a free adoption page where adopters apply and pay online.
It is priced per active foster home, with unlimited staff seats, animals and fosters on the roster. The Starter plan is $39 a month for up to 25 foster homes at a time, with a 30 day free trial. It does not do kennel management or vet billing.
Common questions
What software do small animal rescues use?
Most start with free tools: a shared spreadsheet, a group chat, email and a social media page, often with a listing site for adoptions. As they grow they add either shelter management software, which is built around a facility, or foster-focused software, which is built around foster homes and gives fosters their own app.
Does a rescue without a shelter building need shelter software?
Usually not. Shelter software is built around kennels, intake queues and facility reporting. A rescue where every animal lives in a foster home mostly needs to coordinate those homes, keep each animal's record, and run adoptions, which is what foster-focused software is for.
How much should a small rescue pay for software?
It depends on what it replaces, but a small foster-based rescue should be able to find useful software for well under a hundred dollars a month. Look closely at how it is priced: per animal and per user pricing can grow faster than the rescue does. For example, Second Tail's Starter plan is $39 a month for up to 25 foster homes at a time.
Is there free software for animal rescues?
Some tools have free tiers, and spreadsheets plus a group chat cost nothing. The real cost of free tools is volunteer time spent chasing updates and re-typing information. If one person spends hours a week on that, a paid tool can be cheaper than it looks.
