This page aggregates 6 frequently asked questions from across our guides and calculators.
Cat Vaccination Schedule
Go to Cat Vaccination Schedule →Which vaccinations does my cat need?
Core vaccines (required for all cats) include Rabies and FVRCP (feline viral rhinotracheitis, calicivirus, panleukopenia). Non-core vaccines like FeLV (feline leukemia virus) depend on your region and lifestyle. Our schedule follows WSAVA and AAFP feline guidelines.

When do kittens need their first shots?
Kittens start their vaccination series at 6-8 weeks: 1st FVRCP at 6-8 weeks, 2nd FVRCP at 10-12 weeks, 3rd FVRCP + Rabies at 14-16 weeks. The final dose is given at or after 16 weeks because maternal antibodies can persist until then — giving it earlier risks neutralization.

Does an indoor cat need the same vaccines as an outdoor cat?
Indoor cats still need all core vaccines (FVRCP + Rabies). FVRCP protects against airborne viruses that can enter through windows, and rabies is legally required in most jurisdictions. The difference is non-core vaccines: indoor cats typically do not need FeLV vaccination unless exposed to other cats.

Indoor vs Outdoor Cats
Go to Indoor vs Outdoor Cats →Is it cruel to keep a cat indoors?
No — with proper environmental enrichment, indoor cats live longer, healthier lives. Key needs: vertical space (cat trees), scratching posts, puzzle feeders, window perches with a view, and 15-20 minutes of daily interactive play. This satisfies their core behavioral needs entirely. The average indoor cat lives 12-18+ years vs 2-5 years for outdoor cats.

What is a catio and does it help?
A catio is an enclosed outdoor structure attached to a window, deck, or freestanding that allows cats to experience the outdoors safely. Catios provide fresh air, sunshine, bird-watching, and sensory enrichment without the risks of free roaming. They are the single best compromise for outdoor access.

Toxic Food & Plant Checker
Go to Toxic Food & Plant Checker →What plants are toxic to cats?
The most dangerous plants include True Lilies (Lilium/Hemerocallis — even pollen causes fatal kidney failure), Sago Palm, Azalea, Oleander, Autumn Crocus, Cyclamen, Daffodil/Tulip bulbs, Dieffenbachia, English Ivy, and Pothos. Lilies are the #1 danger — treatment must begin within 6 hours for survival.
