Seven groups of neurological and movement signals: lameness; a cat unwilling to jump up high; sudden hind limb weakness or paralysis; seizures; muscle tremor; drowsiness and coma; and a fall from a height. Aortic thromboembolism in cats is often the first presentation of heart disease, sudden severe lameness with a hot hoof in a horse is an emergency, and an animal that looks normal after a fall may only show internal injury hours later. It also explains why the episode should be filmed as evidence, and that suspected poisoning means bringing the packaging and not inducing vomiting at home, so you can tell what needs leaving now and what needs checking the same day.

Symptom Triage｜Nerves, Gait and Consciousness

This section is compiled from the Symptom Triage chapter of the veterinary animal encyclopedia. The same symptom calls for different handling in different species, and copying what is done for another species can be harmful — first confirm which animal you are dealing with.

Symptom (what the owner sees)	Species where it is common	Possible direction	What the owner can observe / record at home	Matching specialty
Lameness, unwillingness to bear weight on one limb	Dogs and cats (arthritis, trauma, breed-specific orthopaedic disease), horses (laminitis must be ruled out first and is an emergency measured in minutes)	Veterinary visit needed to emergency (sudden severe lameness in a horse with a hot hoof and a bounding digital pulse counts as an emergency)	Whether the lameness came on suddenly or gradually, whether there is obvious trauma, and whether it worsens after activity	Neurology＊ (applies when lameness comes with neurological signs such as dragging a limb or loss of sensation; simple orthopaedic lameness itself is not among the 8 specialties in the original teaching material, see gap A10 rehabilitation medicine)
A cat unwilling to jump up high, slower on stairs, worse tempered	Cats (arthritis is the most common yet most easily overlooked presentation, as cats rarely show obvious lameness)	Veterinary visit needed (arthritis in cats has long been severely underestimated)	Keep a list of "things it used to do and no longer does", and compare month by month how many it can still manage	Neurology＊ (partly applicable for locating pain and differentiating behaviour change; bones and joints themselves are not among the 8 specialties in the original teaching material)
Sudden hind limb weakness or paralysis, severe pain, cold paws	Cats (aortic thromboembolism, ATE, often the first presentation of heart disease), dogs (intervertebral disc disease, IVDD), ferrets (low blood sugar from insulinoma)	Emergency	Record how fast it came on (sudden versus gradual), paw temperature and the response to touch, and any crying out	Cardiology / Neurology (feline ATE originates in heart disease and canine IVDD in the nervous system; the original teaching material lists both)
Convulsions, seizures (loss of consciousness, limb rigidity or paddling movements)	Dogs and cats (epilepsy, low blood calcium, poisoning), ferrets (low blood sugar), birds (hypocalcaemia syndrome, especially in African grey parrots)	Emergency (repeated seizures or one after another is especially urgent)	Film how the episode looks and how long it lasts (it has often stopped by the visit), behaviour before and after, and any contact with suspicious substances	Neurology (epilepsy is core to the original teaching material's listing, an exact match)
Involuntary tremor of the whole body or part of it	Dogs and cats (suspected poisoning, for example pyrethroids or snail bait), reptiles	Emergency (with suspected poisoning, bring the packaging to the clinic and do not induce vomiting or treat at home)	Record the substances that may have been contacted and when, and whether body temperature has risen at the same time	Neurology (tremor is a clinical presentation of abnormal nerve conduction)
Drowsiness, poorer response to being called, confusion or coma	Applies to every species	Emergency	Record how fast consciousness changed, whether the animal can be roused, and mucous membrane colour and body temperature	Neurology / Endocrinology＊ (low blood sugar, diabetic ketoacidosis and adrenal crisis can all present as altered consciousness, and the original teaching material lists a basis for both)
A fall from a height with a completely normal appearance	Cats (high-rise syndrome), birds	Veterinary visit needed (diaphragmatic hernia, lung contusion and mandibular fracture often only show hours later, so "looking fine" is not a reason to skip care)	Watch breathing and activity over the next few hours, and check for nosebleed or bleeding from the mouth	Pathology and Forensics＊ (diagnosis of delayed internal injury)

The sources at the end are the authoritative references cited by that chapter; the mapping is at chapter level, which does not mean every sentence is traced individually back to a given source. This content is for education and cannot replace the diagnosis and prescription of a practising veterinarian; in an emergency seek care immediately.

FAQ

My cat suddenly has weak hind limbs, cold paws and severe pain. Is it a sprain?: This is an emergency. In cats, think first of aortic thromboembolism (ATE), which is often the first presentation of heart disease; in dogs think of intervertebral disc disease, and in ferrets of low blood sugar from insulinoma. Record how fast it came on, paw temperature and the response to touch, and any crying out, then seek care immediately.; 猫の後肢が急に動かなくなり、足先が冷たく強く痛がります。捻挫でしょうか。 — これは急症です。猫では大動脈血栓塞栓症（ATE）を最優先で考えます。心臓病の初発症状であることが多いためです。犬では椎間板疾患、フェレットではインスリノーマによる低血糖を考えます。発症が突然か徐々にか、足先の温度と触った時の痛みの反応、鳴き声の有無を記録し、直ちに受診してください。; My cat suddenly has weak hind limbs, cold paws and severe pain. Is it a sprain? — This is an emergency. In cats, think first of aortic thromboembolism (ATE), which is often the first presentation of heart disease; in dogs think of intervertebral disc disease, and in ferrets of low blood sugar from insulinoma. Record how fast it came on, paw temperature and the response to touch, and any crying out, then seek care immediately.
What should I do while my dog is having a seizure?: Convulsions and seizures are an emergency, and repeated seizures or one after another is especially urgent. The episode has often stopped by the time of the visit, so film how it looks and how long it lasts, and note behaviour before and after and any contact with suspicious substances. If tremor from poisoning is suspected, bring the packaging to the clinic and do not induce vomiting or treat at home.; 犬がけいれんしているとき、何をすればよいですか。 — けいれん・てんかん発作は急症で、発作が連続する、または立て続けに起こる場合は特に緊急です。受診時には止まっていることが多いため、発作の様子と持続時間を動画で記録し、発作前後の行動、疑わしい物質への接触の有無も記録してください。中毒による震えが疑われる場合は包装を持参して受診し、自己判断で吐かせたり処置したりしないでください。; What should I do while my dog is having a seizure? — Convulsions and seizures are an emergency, and repeated seizures or one after another is especially urgent. The episode has often stopped by the time of the visit, so film how it looks and how long it lasts, and note behaviour before and after and any contact with suspicious substances. If tremor from poisoning is suspected, bring the packaging to the clinic and do not induce vomiting or treat at home.
My cat fell from a height but looks completely normal. Does it still need a veterinarian?: Yes. Diaphragmatic hernia, lung contusion and mandibular fracture often only show hours later, so "looking fine" is not a reason to skip care. Keep watching breathing and activity over the next few hours, check for nosebleed or bleeding from the mouth, and have the cat examined.; 猫が高い所から落ちましたが、見た目はまったく正常です。受診は必要ですか。 — 必要です。横隔膜ヘルニア、肺挫傷、下顎骨折は数時間後に現れることが多く、「見た目は大丈夫」を理由に放置しないでください。その後数時間は呼吸と活動性、鼻出血や口腔内出血の有無を観察し、受診して検査を受けてください。; My cat fell from a height but looks completely normal. Does it still need a veterinarian? — Yes. Diaphragmatic hernia, lung contusion and mandibular fracture often only show hours later, so "looking fine" is not a reason to skip care.
