  • Gradual weight loss or changes in appetite
  • Difficulty urinating, straining, or frequent urination

02How to Monitor at Home: What to Observe and When to Seek Emergency Care

Key observations and records you can keep at home — this information helps your vet quickly identify the likely cause and prioritise diagnostic tests.

  • Note the date and time when symptoms first appeared
  • Weigh your pet daily and track any changes
  • Count and record your pet's resting respiratory rate per minute
  • Track changes in appetite, water intake, and feeding frequency
  • Monitor urination frequency, urine volume, and urine colour
  • Collect a fresh urine sample or take photos/video to bring to your appointment

03How Will the Vet Diagnose the Problem? Common Diagnostic Tests

At the clinic, your vet will combine imaging and laboratory tests to identify the cause and rule out urgent conditions.

Physical examination

abdominal palpation, auscultation, and temperature check

Urinalysis

urine routine and culture if indicated

Blood and biochemistry panel

assessing kidney function and overall health

X-ray

checking for urinary tract stones or abdominal structural abnormalities

Abdominal ultrasound

evaluating the kidneys, bladder, and urinary tract

Blood pressure measurement and advanced imaging (CT) if necessary

It is advisable to visit a specialist clinic equipped with imaging and laboratory facilities

04How to Treat and Care for Your Pet After Diagnosis? Medication, Diet, and Home Care Guide

Treatment and follow-up will be tailored to the underlying cause; home care and regular check-ups are equally important to prevent recurrence.

  • Adjust to a prescription diet and manage water intake as directed
  • Follow all medication instructions and attend scheduled follow-up appointments
  • Regular urinalysis and blood tests to monitor kidney function
  • Home care: keep the litter area clean and monitor urination habits
  • Arrange specialist referral for further imaging or urological procedures if needed
  • Return to the vet immediately if symptoms worsen or any warning signs appear
