The TANDEM Cat® Transitional Stress Anorexia (TSA) Protocol provides a structured, trauma-informed framework for identifying and reversing early anorexia in boarding cats before dehydration, hepatic lipidosis, or medical collapse occur.
The protocol recognizes that many cats stop eating during the first several days of boarding not because of primary disease, but because of environmental transition, stress, nervous system dysregulation, and loss of familiarity.
TSA is treated as a clinical condition requiring active observation and intervention.
Transitional Stress Anorexia (TSA) is a temporary reduction or cessation of food intake associated with environmental change, separation from home, routine disruption, or stress-related withdrawal.
TSA may occur in otherwise healthy cats.
Unlike anorexia caused by primary medical disease, TSA often improves with structured support, hydration, relationship-based care, and nutritional intervention.
Cats are uniquely vulnerable to the consequences of prolonged anorexia.
Untreated anorexia may contribute to:
Dehydration
Weight loss
Weakness
Gastrointestinal dysfunction
Hepatic lipidosis
Hospitalization
The goal of the TSA Protocol is intervention before these complications occur.
Hiding
Reduced interaction
Withdrawal
Reduced environmental engagement
Increased vigilance
Shutdown behavior
Refusal of meals
Partial meal consumption
Refusal of treats
Reduced interest in food
Eating only when staff are present
Tension
Decreased grooming
Reduced mobility
Altered posture
Reduced exploratory behavior
Higher-risk cats may include:
Senior cats
Medically complex cats
Diabetic cats
Cats with previous anorexia history
Cats with anxiety or stress sensitivity
Cats boarding for the first time
Cats with recent environmental changes
Initiate when:
A meal is partially consumed
Food interest decreases
Behavioral withdrawal begins
Actions:
Increase monitoring
Offer preferred foods
Offer treats
Encourage environmental comfort
Document intake carefully
Initiate when:
A cat misses meals
Food intake continues to decline
Actions:
Offer warmed food
Offer high-value proteins
Offer alternative textures
Hand-offer food when appropriate
Increase human presence and engagement
Document response.
Initiate when:
Voluntary intake remains inadequate
Early anorexia is developing
Actions:
Begin trauma-informed manual feeding
Use approved supported-feeding techniques
Move slowly and maintain regulation
Prioritize consent-based pacing whenever possible
Supported feeding serves both diagnostic and therapeutic functions.
Many cats resume voluntary eating after one to three supported feeding sessions.
Initiate when:
Intake remains poor
Hydration concerns emerge
TSA appears likely to continue
Actions:
Administer subcutaneous fluids when authorized
Continue nutritional support
Continue behavioral monitoring
Hydration is used proactively, not reactively.
Initiate when:
Anorexia persists
Clinical deterioration occurs
Medical concerns emerge
TSA no longer appears to be the sole explanation
Actions:
Notify leadership
Contact veterinarian when appropriate
Follow medical escalation procedures
Document:
Food offered
Food consumed
Behavioral observations
Manual feeding sessions
Fluid administration
Escalation decisions
Guardian communications
Accurate documentation is essential for continuity of care.
TSA Protocol initiated following refusal of breakfast and dinner on Day 2 of boarding. Cat remained withdrawn but alert. High-value foods offered without success. One supported feeding session performed with good tolerance. Cat consumed small amount voluntarily later that evening. Continued monitoring planned.
A missed meal is not a neutral event.
It may represent the beginning of TSA.
Prevention is easier than rescue.
Early support reduces the likelihood of escalation.
Changes in behavior often precede physical decline.
Observe carefully.
Food, hydration, relationship, pacing, and nervous system regulation are clinical tools.
The goal is stabilization, not compliance.
When identified and treated early, TSA frequently resolves without:
Sedation
Hospitalization
Feeding tubes
Emergency intervention
Many cats return to voluntary eating after structured, early intervention.
Transitional Stress Anorexia is a predictable and treatable response to environmental transition.
The TANDEM Cat® TSA Protocol provides a structured, repeatable approach for identifying early anorexia, intervening before collapse, and supporting cats through boarding with dignity, safety, and trauma-informed care.
