Weak back legs, limping, or a sudden change in jumping means pain, injury, or weakness until your vet helps sort it out.
This is not a diagnosis page. It helps you organize what changed so your vet conversation is clearer.
Compare normal movement with today: weight bearing, jumping, stairs, paw tenderness, swelling, wounds, hiding, appetite, and whether your cat can reach food, water, and litter.
Treat symptom pages as triage support, not a diagnosis. Appetite, water, urine, stool, breathing, mobility, gums, pain signs, and energy matter more than one isolated symptom word.
Limit jumping, keep resources close, and check only what your cat calmly allows. Do not give human pain medicine to a cat.
Write down timing, frequency, appetite, litter use, breathing, movement, and any trigger you saw. A short video is often more useful to your veterinarian than a long description.
Tell the clinic which leg or movement changed, when it started, whether your cat can bear weight, recent jumps or falls, paw or nail changes, appetite, and litter access.
Start by deciding whether this can wait. Breathing trouble, urine changes, appetite loss, severe pain, collapse, toxin exposure, or sudden decline means the next step is a vet call.
Call your veterinarian for sudden, severe, persistent, or worsening limping, weakness, swelling, wounds, suspected falls, appetite loss, or obvious pain.
Do not monitor at home when breathing is hard, gums look pale or blue, the cat cannot stand, pain is obvious, appetite stops, urination changes, or symptoms escalate.
