A business plan is a form of document made for the purpose of income objectification and expenses rationalisation. Such a plan is a precondition for defining goals and strategies of a company in order to eventually propose viability and sustainability of a certain business idea. In veterinary medicine, private veterinary clinics are recognised as a primary form of the veterinary trade, and as such they require a business plan. Unfortunately, in Croatia, there is a lack of official data on the relative or absolute number of pets. So, in order to estimate a potential market volume, one must use official data of the European Union about the number of pets per household. The veterinary clinic CataVet is a potential business venture placed in Savica, an urban settlement in Zagreb with a large number of potential clients with the city district Trnje being the primary market, and the city of Zagreb being the secondary market. A business plan as well requires a market analysis and recognition of the internal and external factors which could affect the outcome of the business venture. Considering the CataVet veterinary clinic, its strenghts are state of the art diagnostics technology, accessible location, interdisciplinary education of the staff, large offer of nonmedical services at the same location and a strong focus on the development of digital marketing. In the spirit of a holistic approach in taking care of animal welfare, besides providing healthcare for its patients, the veterinary clinic CataVet will be providing services of pet haircuts, dog trainings at the nearby dog agility park and a pet hotel. The clinic will as well comprise a pet shop and a veterinary drug store. With sources of funding being credit, financial leasing and personal resources, projections of income and outcome and financial reports were made in order to assure feasibility and profitability of the business venture.
