Spring is 2 problems arriving on the same day: a coat that is being pushed out, and windows that get opened for the first time in months. Both are mechanical, both have numbers attached, and both are cheapest to handle on a 2-week loop rather than after something goes wrong.
Why Spring Runs on a 2-Week Clock
Once daylight passes roughly 12 hours, most cats begin dropping the winter coat, and the loose phase lasts 3-4 weeks. Brushing once a week during that window removes very little; the undercoat sheds into the room, onto bedding, and down the cat's own throat. Two weeks is also the interval at which screen mesh, frame clips and balcony netting fail in ways you can still see by hand before a cat finds them.
Temperature moves the schedule more than the calendar does. A flat that jumps from 18 C to 26 C in 5 days will trigger shedding faster than a cool March. Track the indoor high, not the date. Humidity matters for the coat too: 40-60% keeps skin supple, under 35% raises static and dander, and above 65% a long coat starts matting at the armpits within 2-3 days.
The 8-Point Checklist, Every 2 Weeks
- 1. Brushing load. Short coat: 3 sessions a week, 5-8 minutes each. Semi-long: 4 sessions, 10 minutes. Long coat: daily, 10-15 minutes. A 10-minute session should produce a golf-ball of loose hair; less means the tool is wrong, not the cat.
- 2. Two tools, not five. An undercoat rake with 9-12 mm teeth plus a slicker brush covers 90% of the job. Replace the rake when teeth bend or the coating wears at 6-9 months.
- 3. Window screens, 4-point test. Mesh size, frame gap, clip count, latch load. Detail below.
- 4. Balcony netting. 3 mm mesh minimum, anchors every 50 cm, tension checked by hand at 2 points. Re-tie any anchor that moves more than 2 cm.
- 5. Hair in machines. Dryer lint filter every 2 loads, washing machine filter every 30 days, vacuum the fridge coil grille twice a season.
- 6. Hairball count. One vomited hairball a month is ordinary in spring; 2 or more a month, or any retching with nothing produced, needs a vet visit. Malt paste 2-3 times a week helps, 2 cm per dose.
- 7. Parasite start date. Begin monthly spot-on on the first day the outdoor high passes 15 C, and keep it going to the first frost. Weigh the cat and dose by kg, not by age label.
- 8. Plants and balconies. Check every pot and cut flower against the toxic list before it comes inside; a lily is a 24-hour emergency, not a decoration.
Shedding Load by Coat Type
| Coat | Sessions per week | Minutes per session | Hair per session | Main tool |
|---|---|---|---|---|
| Short, single coat | 3 | 5-8 | golf ball | Rubber curry comb |
| Short, double coat | 4 | 8-10 | 2 golf balls | Undercoat rake, 9 mm |
| Semi-long | 4 | 10 | 3 golf balls | Rake plus slicker |
| Long | 7 | 10-15 | 4 golf balls | Slicker plus metal comb |
| Senior, thin coat | 3 | 5 | 1 golf ball | Soft bristle brush |
The 4-Point Window Test
Mesh. Under 1.2 mm stops a paw; 2 mm insect mesh stretches and tears at a claw. Frame gap. More than 5 mm between screen frame and window frame gives a cat a purchase point. Clips. At least 4, one per side, and none cracked. Latch load. A determined cat can push 4-5 kg sideways against a screen; press each corner with 5 kg of hand force and watch for movement.
Open windows tilt, not slide, if the flat is above the second floor. A 4 m fall onto concrete is survivable but commonly means a fractured jaw or hard palate, and the bill runs into four figures. The full failure list is in the window risk guide.
Tools That Remove Undercoat Without Cutting Guard Hair
Clippers are the wrong tool for a shedding cat: shaving a double coat removes the insulation that keeps the cat cool in July and can leave patchy regrowth for 6-12 months. Use an undercoat rake with 9-12 mm teeth, work in 5 cm strips along the direction of the coat, and stop when the rake stops filling. A slicker follows for the top coat, 3-4 passes per zone. The tool comparison is in the shedding tool guide.
Brush outside or in a bathroom with the door shut, and wipe the surface afterwards with a damp cloth. Loose undercoat at 2-4 cm length floats for hours and settles on every horizontal surface within 3 m.
Three Risk Categories
Falls and screens. Spring is the season of the failed screen: 1 clip cracked, 5 mm gap, and a cat 4 m down. Any cat that has fallen needs a vet check within 24 hours even if it walks normally, because hard palate fractures and pneumothorax do not always show at once.
Ingestion. Hair is the mild version; thread, tinsel, Easter grass and 30 cm of ribbon are the surgical version. A cat that retches 3 times in an hour, or vomits after eating for 2 days, is a same-day appointment.
Toxicity. Spring brings lilies, tulips, azaleas, cocoa mulch and lawn fertilizer. Lily pollen on a whisker is enough; permethrin flea products meant for dogs kill cats at doses sold for a 10 kg dog. Check the toxic list before the first garden trip.
When Shedding Is Not Seasonal
Three patterns are not spring: bald patches larger than a coin, coat that stays thin past 6 weeks, and shedding with weight loss or a ravenous appetite. Those point at thyroid, kidney or skin disease and need bloodwork, not a better brush. A cat over 10 years old that suddenly sheds in clumps should be seen within 2 weeks.
Two Weeks From Now
- Put the 8 items on a repeating 2-week reminder, same day each time.
- Brush today and weigh the hair; if it is under a golf ball, change the tool.
- Press all 4 corners of every screen with 5 kg of hand force.
- Start monthly parasite control on the first 15 C day.
- Clear lilies, tulips and azaleas out of the house this week.

Frequently asked
How often should I brush a cat during spring shedding?
Three sessions a week for a short single coat, 4 for a double coat or semi-long, and daily for a long coat, at 5-15 minutes each. A 10-minute session on a double coat should fill about 2 golf balls of loose hair. If it does not, the tool is the problem: use a 9-12 mm undercoat rake rather than a soft brush that only smooths the surface.
Do window screens really stop a cat from falling?
A good screen does, a cheap one does not. Look for mesh under 1.2 mm, a frame gap under 5 mm, at least 4 intact clips, and no movement when you press a corner with 5 kg of hand force. Standard 2 mm insect mesh stretches at a claw and pulls out of the frame. Test every screen on a 2-week loop, and open only tilt windows above the second floor.
Is it safe to shave a cat in spring to reduce shedding?
Usually not. A double coat insulates against heat as well as cold, and shaving it can leave patchy regrowth for 6-12 months plus a higher risk of sunburn on pale skin. Undercoat rakes and slickers remove the loose layer without cutting guard hair. Shaving is a veterinary decision for severe matting or skin disease, not a shedding shortcut.
