Excessive Grooming
If your sugar glider is grooming excessively to the point of losing fur or creating hot spots, it may be due to an allergic reaction. This behavior is typically a result of them attempting to soothe their irritated skin.
Wheezing and Coughing
Respiratory issues such as wheezing, coughing, and difficulty in breathing can also indicate an allergy. These are serious symptoms as sugar gliders are very prone to respiratory illnesses.
Redness or Swelling
Redness, swelling, discomfort or any abnormalities on the skin can be a symptom of an allergic reaction. It may be due to contact with an allergen or an allergic reaction to something ingested.
Change in Appetite
A sudden change in appetite can be another indicator. If your sugar glider is eating significantly less or more than usual, it could be because they are reacting to something in their diet.
Vomiting or Diarrhea
Vomiting and diarrhea are indicative of gastrointestinal distress, which could be from ingesting something to which they are allergic. It's crucial to monitor these signs as they can quickly lead to dehydration.
Behavioral Changes
Changes in regular behavior like lethargy, aggression or depression also indicate something is wrong with the sugar glider's health. These changes often occur when the sugar glider is under stress, which can be caused by an allergy.
