Post-Op Rehab: a 6-Week Load Ladder for Cats

Six weeks is the usual shape of a post-operative rehab block: 2 weeks of protected rest, 2 weeks of controlled loading, 2 weeks of rebuilding strength before a return to normal activity. This plan assumes routine orthopedic or soft-tissue surgery, a cat eating and using the box unaided, and a day 10 to 14 recheck with no swelling, no discharge and an intact suture line. A cat that fails that recheck needs a new plan, not a faster one.

Three numbers control the block: sessions per day, load per session, minutes per session. Owners obsess over which exercise to pick. The cat recovers on the dose.

Week by week: what changes

Weeks 1 and 2 cover standing, walking 5 steps to the bowl, and a dry incision. Range of motion is passive, 2 to 3 minutes per joint, once or twice a day. The cat lives in 1 room of 4 to 6 square meters, box 1 to 2 meters from food, nothing above 25 cm to jump on.

Weeks 3 and 4 add active work: 3 walks of 3 to 5 minutes on carpet, no stairs, no jumping above 30 cm. Weeks 5 and 6 add resistance and balance: 2 sessions of 10 to 12 minutes, with 1 rest day in 7.

Stairs wait until week 6, and jumping above 40 cm until week 8 in most surgeon protocols. Those 2 limits are the ones owners break first, usually on day 18, when the cat finally looks normal.

Week	Sessions per day	Sessions per week	Minutes per session	Load target	Advance when
1	3	21	3-4	0% added, passive range only	Stands to eat 2 meals in a row
2	3	21	4-5	10-15% of body weight	Walks 10 steps without a sling
3	2	14	6-8	20-25% of body weight	Uses the leg in 8 of 10 steps
4	2	14	8-10	30-35% of body weight	Lameness 1 of 4 or better
5	2	14	10-12	40-50% of body weight	Jumps 20 cm onto a step, 3 times
6	1-2	9-12	12-15	60-70% of body weight	Two 10-minute walks, no stiffness at 2 hours

The load column is the share of body weight the operated limb carries during the drill, checked on a bathroom scale under the paw. It is not walking load: a healthy cat puts 60 percent of body weight on each hind limb at a trot.

Reps and sets: 3 sets of 5

From week 2 to week 6 each exercise is dosed as 3 sets of 5 reps, 30 to 45 seconds between sets, 2 minutes between exercises. A set of 5 weight shifts takes 20 seconds, so one exercise runs 3 to 4 minutes with rest. Four exercises fill a 12 to 15 minute session.

Five reps is deliberately low. Push a cat to 15 and you get 3 clean ones plus 12 sloppy ones, and sloppy reps rehearse the wrong pattern. If 5 feel easy, add load, never reps. Cap at 3 sets of 8 and stop the session at 15 minutes.

Why short sessions win

Healing tissue tolerates frequency better than volume. Four 5-minute sessions at 8 am, 1 pm, 6 pm and 10 pm give 20 minutes of input with 4 recovery windows; 1 block of 20 minutes gives the same minutes and no recovery, plus a much higher chance of next-day soreness.

Use the 2-hour rule as the brake: if the cat is stiffer 2 hours after a session than before it, that session was too long or too heavy. Cut the next one by 30 percent and hold the week. A stiff day costs 3 days; a pushed week costs 10.

The 5 gates for adding load

• Gate 1: eats 2 full meals and uses the box unaided.
• Gate 2: loads the limb in 8 of 10 steps over 10 steps.
• Gate 3: lameness 1 of 4 or better on a 10-second video.
• Gate 4: no swelling at 24 hours after the last session.
• Gate 5: jumps 20 cm without hesitation, 3 times.

Move 1 gate at a time and hold each new load 4 to 5 days. Clearing 4 of 5 gates and staying put for another week is normal, not a failure. Two weeks with no gate cleared means a reassessment, not more push.

Signs that mean stop today

Stop the session and call the clinic the same day for any of these: the incision opens, discharges pus or bleeds more than a spot; the joint swells over 1 cm; the cat cries or bites at the leg during a passive stretch; the paw is cool or the pads pale; the cat refuses food for 2 meals; or a limb that was weight-bearing stops for more than 12 hours. Sudden loss of function at any week is a phone call, not a rest day.

Soreness that settles within 2 hours and is gone by morning is expected in weeks 3 and 4. Anything lasting past 12 hours, or arriving with a fever above 39.2 C, is not.

Clear the plan before day 1

Every number above is a template, not a prescription. Ask the surgeon or a rehab therapist to sign off at the day 10 to 14 recheck, with a load target for this cat, this implant, this incision. A repaired femur, a skin graft and a cystotomy do not share a ladder, and a 4 kg cat with 2 operated limbs is not a 4 kg cat with 1. Early checks are in the post-op care by day schedule; the first 7 days at home are covered in the new cat first week guide.

What 6 weeks costs

Twenty-one sessions a week for 2 weeks plus 14 a week for 4 weeks is 42 plus 56, so 98 sessions, or 8 to 15 hours of hands-on time at 4 to 12 minutes each. Rehab visits run 60 to 120 USD, usually 1 every 2 weeks, so 3 visits add 180 to 360 USD. A log of date, load, reps and a 0 to 4 lameness score makes those 98 sessions readable in 2 minutes; the wider budget sits in the cat cost calculator.

Seven steps for today

1. Weigh the cat, write the number on the log.
2. Set the room: mat, low box, food 1 to 2 meters away.
3. Book the day 10 to 14 recheck, ask for a written load target.
4. Set 3 alarms a day for weeks 1 and 2, then 2.
5. Run 3 sets of 5, rest 30 to 45 seconds, 2 minutes between drills.
6. Score lameness 2 hours after the last session.
7. Hold each load 5 days, cut 30 percent after a stiff day.

Review at day 7, 14, 21, 28, 35 and 42. Six reviews, 6 decisions, and a cat that reaches week 7 with 4 working limbs.
