Cocoa seems to have been in season for a longer time than usual. What is the normal timeframe for a female piggy to be in season? Should I worry if it is longer than the average time?

Hi

How old is Cocoa and how long has she been in season? A season typically lasts only 15-17 hours but in a strong season, sows can be somewhat cranky in the run up, which typically translates to about 2 days of mayhem.

Any season that seems to last days or weeks is caused by ovarian cysts.
The most common age for homonal cysts is from about 18 months to 4 years with the peak around 2-3 years but they are known to appear earlier or later than that.
These are generally smaller cysts causing high hormone output when they start growing but by far not all will ever cause any or all of the typical symptoms commonly associated with ovarian cysts. Later in life non-hormonal fluid-filled cysts (that can cause problems because of the size they can grow to) will become the most common type of ovarian cyst of all next to a thankfully small percentage of cancerous cysts.
If you suspect ovarian cysts and if they become very disruptive and also lead to weight loss, please see an exotics vet or a vet experienced with guinea pigs if possible.

Here is more information on strong seasons and ovarian cysts (with treatment options): Sows: Behaviour and female health problems (including ovarian cysts)
