This model requires free or very low cost space. 600 to 1200 square feet is optimum. Less is more; a smaller space that is easy to cool and heat is far better than a larger space with high cooling/heating costs. High overhead, even if the space is free, increases the cost per surgery and can make the entire program unsustainable.
A few things you cannot do without…running water, a moppable floor and heat and air conditioning are a matter of disease control and safety for the pets. You can be creative with walls—for example, separate spaces (for example to shield cats from view of dogs) can be made out of PVP pipe and sheets or shower curtains.
Convenient parking is important; however, if there are very limited spaces, the clients’ arrival times can be staggered.
Because free (or nearly free) clinic space keeps the overhead low, and pay is per diem, this model can withstand slower periods while it opens and then grows; it sustains on a small number of staff members and does not require a large volume of surgeries to keep the doors open. Due to very low cost (or free) overhead a mini clinic should not cost money on days it is closed.
