Start with what you have noticed and find the appropriate next step.
Act on urgent changes.
Difficulty breathing, collapse, repeated unsuccessful attempts to urinate, seizures or suspected poisoning need urgent veterinary contact. Call before travelling when possible; do not wait for an online reply.
If your cat strains but passes little or no urine, call a Kings branch immediately and arrange urgent assessment. Do not wait for an online booking reply or try to squeeze the bladder.
Call urgently if your cat becomes very weak, repeatedly vomits, stops eating or produces very little urine. A sudden deterioration needs assessment even when kidney disease has already been diagnosed.
Open-mouth breathing, obvious effort to breathe, collapse or rapid deterioration need emergency assessment. Call immediately; do not wait for a routine appointment or try human cold medicines.
Arrange prompt advice for spreading skin lesions or an unwell kitten. Call urgently for severe weakness, breathing problems or another sudden deterioration; ringworm does not explain every sign of illness.
A cat with suspected or diagnosed diabetes who vomits, stops eating, becomes weak or collapses needs urgent veterinary advice. Do not change prescribed doses or give extra medicine without instructions.
Call promptly if your cat cannot eat, has facial swelling or is bleeding from the mouth. Severe weakness, collapse or breathing difficulty need emergency assessment.
Call promptly for severe pain, sudden head tilt, loss of balance or an ear problem with marked illness. Do not put leftover drops or cleaning products into a painful ear without advice.
Sudden facial swelling, difficulty breathing or collapse need emergency assessment. Arrange prompt care for painful, rapidly worsening skin, extensive wounds or itching accompanied by marked illness.
Call immediately for an unwell puppy with repeated vomiting or diarrhoea, especially with weakness or blood. Mention possible parvovirus before arriving so the team can advise safe reception and isolation arrangements.
Call urgently for repeated vomiting, inability to keep water down, blood or black stool, marked weakness, a swollen or painful abdomen, unproductive retching, or possible poison or foreign-object ingestion.
Move your dog out of the heat, call an emergency vet and begin cooling with water cooler than the dog and airflow while arranging transport. Do not delay veterinary care to see whether the dog improves.
Call promptly for facial swelling, mouth bleeding, a broken tooth with pain or difficulty eating. Severe weakness, collapse or breathing difficulty needs emergency assessment.
Contact a veterinarian promptly when your cat stops eating. Do not wait for 24 hours to pass: going without food for that long can already harm an adult cat, and young kittens can deteriorate sooner. Difficulty breathing or repeated attempts to pass little or no urine need immediate emergency care.
