This includes seasons of the year, vacations and holiday schedules, fiscal year and tax season, and Canadian geese migration patterns. Did Canadian geese and fiscal year make you smile? Well, the geese are the only one I haven't actually heard from the breeders before. All the other reasons above are the actual beliefs that breeders have about why their sales fail and puppies wait for their owners longer. In reality, there are future owners that want to get a puppy or a kitten while they are on vacation, and not the other way around. Besides, there are conscious and responsible future owners that are willing to wait for a puppy or kitten from your kennel or cattery even if it takes more than half a year.
The only thing that has been truly seasonal is the pandemic. The market has changed indeed, and the demand for pets has increased significantly.
