Hairball Prevention in Cats: Causes, Treatment & Care Tips
Why do cats throw up hairballs? Learn about causes, risks, and effective prevention strategies including diet, grooming, and supplements.
What Are Hairballs? How They Form
During grooming, a cat's barbed tongue picks up loose fur that is then swallowed. Most swallowed hair passes through the digestive tract and exits in the stool, but when too much accumulates it forms a hairball (trichobezoar) in the stomach and is vomited up.
The occasional hairball — once or twice a month — is considered normal. However, if your cat is vomiting hairballs weekly or more, retching without producing anything, or experiencing appetite loss, a hairball problem may be developing.
If a hairball becomes lodged in the intestines, it can cause a bowel obstruction requiring emergency surgery. Long-haired breeds such as Persians, Maine Coons, and Norwegian Forest Cats face a higher risk and benefit greatly from routine preventive care.
Track your cat's vomiting patterns to distinguish normal hairball episodes from vomiting caused by illness.
High-Risk Cats & Warning Signs
High-Risk Cats
- Long-haired breeds: Persians, Maine Coons, Ragdolls, and similar
- Over-groomers: Cats that lick excessively due to stress or skin conditions
- Cats in shedding season: Spring and fall coat changes increase loose fur
- Senior cats: Reduced gastrointestinal motility makes it harder to pass hair
Warning Signs That Require Attention
- Frequent retching or gagging without producing a hairball (dry heaving)
- Loss of appetite lasting 2+ days
- Constipation or difficulty defecating
- Abdominal distension
- Lethargy or reluctance to move
These symptoms may indicate a hairball is lodged in the digestive tract, and intestinal obstruction is an emergency. Seek veterinary care immediately. X-rays or ultrasound will reveal the hairball's location and size, and endoscopic removal or surgery may be necessary.
Effective Hairball Prevention Strategies
Brushing
Regular brushing is the foundation of hairball prevention. Short-haired cats benefit from brushing once or twice a week, while long-haired cats ideally need daily sessions. Making coat care a daily routine significantly reduces the amount of fur your cat swallows. Increase frequency during shedding season.
Dietary Strategies
- Hairball-control food: Formulated with extra fiber to help move hair through the digestive tract
- Wet food: The added moisture supports gut motility and smoother passage of fur
- Cat grass: Some cats find that nibbling on cat grass helps them bring up hairballs more easily
Supplements & Pastes
- Hairball remedy paste: Petroleum-based lubricants that ease hair passage. Can be given 2-3 times per week as a treat.
- Fiber supplements: Soluble fibers like psyllium improve bowel regularity
Additional Measures
- Encourage indoor exercise to keep the digestive system active
- Increase water intake
- If stress-driven over-grooming is the cause, identify and address the source of stress
If prevention efforts don't help, consult your vet to rule out skin conditions or allergies driving excessive grooming.
