Health by Species
Cats and dogs have very different health needs. Our veterinary-reviewed guides are organized by species for accurate, relevant information.
Cat Health Guide
From litter box changes that signal illness to weight management, dental care, and understanding feline-specific diseases like FIV and hyperthyroidism.

Hip dysplasia, bloat, skin conditions, and breed-specific risks — plus the vaccination and parasite prevention schedules every dog owner needs to know.
Explore dog health →Core Pet Health Topics
The health areas that matter most for cats and dogs, based on guidance from the AVMA and ASPCA.
Nutrition & Weight Management
Obesity affects over 50% of pets in the US according to the Association for Pet Obesity Prevention. Proper nutrition prevents diabetes, arthritis, and heart disease. See our cat feeding guide and dog nutrition tips.
Dental Health
The AVMA recommends daily tooth brushing and annual professional dental cleanings. Untreated dental disease can lead to heart, kidney, and liver complications.
Vaccinations & Parasite Prevention
Core vaccines (rabies, FVRCP for cats, DHPP for dogs) are essential. The AAHA Vaccination Guidelines provide the most current evidence-based schedules.
Mental Health & Behavior Connection
Behavioral changes are often the earliest signs of physical illness. Our cat behavior guides and dog behavior guides explain how to distinguish behavior from health issues.
Senior Pet Care
Pets age faster than humans — a 7-year-old dog is roughly equivalent to a 50-year-old human. The Cornell University College of Veterinary Medicine recommends bi-annual checkups after age 7.
Reproductive Health & Spay/Neuter
The ASPCA strongly recommends spay/neuter to prevent reproductive cancers and reduce behavioral issues linked to hormones. Timing varies by breed and size.
💡 Veterinary Insight“The single most impactful thing a pet owner can do is establish a relationship with a veterinarian before their pet is sick. A baseline exam lets us detect subtle changes over time that would otherwise go unnoticed until a condition becomes serious — and far more expensive to treat.”

Warning Signs That Need Immediate Veterinary Attention
These symptoms may indicate a medical emergency. Contact your vet or an emergency animal hospital immediately. Many of these signs also overlap with behavioral stress — see our cat stress guide and dog anxiety guide.

- Vomiting more than twice per week or blood in vomit
- Hiding continuously for more than 24 hours
- Excessive thirst or urination (signs of diabetes or kidney disease)
- Labored breathing or open-mouth breathing (always an emergency)

Preventive Care: What Your Pet Needs & When
Based on guidelines from the AAHA, AVMA, and American Association of Feline Practitioners (AAFP).
Annual Wellness Exam
Full physical assessment including weight, dental evaluation, organ palpation, and bloodwork baseline. Essential for catching disease before symptoms appear.
Every 12 months (adult) · Every 6 months (senior)Core Vaccinations
Rabies, FVRCP (cats), and DHPP (dogs) are non-negotiable. Non-core vaccines (FeLV, Bordetella, Leptospirosis) depend on lifestyle and risk as per AAHA guidelines.
Per vet schedule · Varies by vaccineParasite Prevention
Year-round flea, tick, and heartworm prevention is recommended by the Companion Animal Parasite Council (CAPC) for all cats and dogs, regardless of lifestyle.
Monthly (most products)Dental Cleaning
Professional cleaning under anesthesia removes tartar below the gumline that brushing cannot reach. The AVMA recommends professional cleaning at least annually.
Annual professional · Daily brushing at homeMicrochipping
A permanent form of identification endorsed by the ASPCA. Microchipped pets are 2.5x more likely to be reunited with their owners if lost.
Once (update registration annually)Bloodwork & Urinalysis
Annual bloodwork detects kidney disease, liver issues, thyroid disorders, and diabetes — often before any visible symptoms. Critical for cats, who hide illness instinctively. See our cat health behavior guide.
Annually (adult) · Every 6 months (senior)Featured Pet Health Guides
