How to Run a Profitable Cattery: Tracking Expenses, Income and Profit per Litter

Most breeders start because they love their breed, not because they want to run a business. But every cattery has real costs, and those costs add up faster than most people expect. Knowing your numbers helps you price kittens fairly, plan for emergencies, keep your cattery sustainable, and stay on the right side of tax rules.

This guide explains where cattery money really goes, how to calculate profit or loss per litter, how to price kittens with confidence, and the simple bookkeeping habits that make it all manageable — whether you have one queen or a full breeding programme.

Why tracking money matters

Without records, it is easy to believe a litter made a healthy profit because six kittens sold for a good price. Once you add stud fees, health testing, scans, vaccinations, food, heating and the occasional emergency vet visit, many litters barely break even — and some make a loss.

Accurate figures help you make better decisions: whether your kitten prices are realistic, whether a particular stud is worth the fee, how many litters per year are sustainable, and how much to keep aside for emergencies. They also make tax time far less stressful.

The real costs of a litter

Before mating

• Health testing and DNA tests for the queen and stud
• Stud fee, or the cost of keeping your own stud
• Travel to and from the stud
• Pre-mating vet checks and vaccinations

Pregnancy and birth

• Pregnancy scans and vet checks
• Extra high-quality food for the queen
• Kittening box, heat pads and supplies
• Emergency costs such as a caesarean section — rare, but expensive

Raising the kittens

• Kitten food from weaning to collection, often 13 weeks or more
• Litter, bedding and cleaning products
• Vaccinations, microchips and vet health checks for every kitten
• Worming and flea treatments
• Registration fees and transfers
• Heating and electricity

Running the cattery

• Advertising, website and photography
• Breed club and registry memberships
• Show entry fees and travel
• Insurance
• Software and printing for pedigrees and kitten packs

Direct costs versus shared costs

Some costs belong clearly to one litter — the stud fee, the scan, each kitten's vaccinations. These are direct costs. Others are shared across the whole cattery — food for your adult cats, memberships, insurance and heating.

To see the true profit of a litter, add a fair share of the shared costs. A simple method is to divide yearly shared costs by the number of litters you produce, or by the number of months each litter is in the house. It does not need to be perfect; it needs to be consistent.

Working out profit per litter

The calculation is straightforward:

• Add every income linked to the litter — kitten sales, deposits kept, stud fees received
• Subtract every direct cost tagged to that litter
• Subtract the litter's share of shared costs
• The result is the litter's profit or loss

A worked example

Imagine a litter of five kittens sold at £900 each, giving £4,500 of income. Direct costs include a £500 stud fee, £300 of health testing, £150 in scans, £600 in vaccinations, microchips and vet checks, £450 of food, litter and supplies, and £150 of registration. That is £2,150. Add £700 as the litter's share of yearly costs such as insurance, memberships, heating and advertising, and total costs reach £2,850 — leaving £1,650.

Now imagine the same litter with an emergency caesarean costing £1,200, or only three kittens. The profit shrinks quickly, which is why tracking every litter separately matters.

Pricing kittens fairly

Knowing your cost per kitten gives you a solid floor for pricing. From there, consider breed demand, the quality and health testing of the parents, show results, registration type and what reputable breeders in your area charge. Kittens with breeding rights are typically priced higher than pet kittens because of the responsibility and value involved.

Avoid underpricing to sell quickly. Low prices can attract buyers who have not budgeted for a pedigree cat's ongoing care, and they make it harder to cover the occasional expensive litter.

Simple bookkeeping habits that help

• Record expenses on the day they happen, not at the end of the year
• Photograph or keep every receipt
• Tag each expense to a litter or to general cattery costs
• Record deposits as soon as they are paid, with the buyer's name
• Review your figures monthly so surprises are caught early
• Export a yearly report for your accountant before tax time

Tax and record keeping

Whether you need to declare breeding income depends on your country and on whether breeding counts as a hobby or a trade. In the UK, regular breeding with a profit motive may need to be declared, and some councils require a licence for breeding cats commercially. Keeping clean records makes these questions easy to answer. Speak to an accountant for advice specific to your situation.

Growing a sustainable cattery

Profit is not the main goal for most breeders, but sustainability is. Steady records help you build an emergency fund, invest in health testing, import new lines to improve diversity, and plan fewer, better litters. Combine good finances with a strong public cattery page to reach the right buyers and a buyer waiting list to reserve kittens early, so fewer kittens stay beyond 13 weeks.

Let the app do the maths

Purrline's cattery accounts track income and expenses in £, $ or €, tag them to litters, and show profit per litter and per year automatically. You can export everything to a spreadsheet for your accountant in one tap. Litters link to your litter and kitten tracker, and stud matings connect to your heat cycle and mating reminders, so costs are captured as you go.

Key takeaways

• Most litters cost far more than breeders expect once health testing and care are included
• Separate direct litter costs from shared cattery costs, and share them out consistently
• Calculate profit per litter, not just per year
• Use your cost per kitten as the floor for pricing
• Record expenses the day they happen and review monthly
