home Home Care Tips

1. Do the ear-and-nose check — Compare your cat's ear warmth and nose moisture to what's normal for them 2. Check the gums — Press a finger against the gums; they should be pink and moist. Dry, pale, or red gums are concerning 3. Monitor water intake — Offer fresh water and wet food to prevent dehydration 4. Provide a comfortable resting area — Keep your cat in a quiet, temperature-controlled room 5. Never give human medications — Acetaminophen (Tylenol) is toxic and potentially fatal to cats. Ibuprofen is also dangerous 6. Invest in a pet thermometer — Digital rectal thermometers designed for pets are inexpensive and the gold standard
