Catching my cat still and not engaged while he's awake is the only difficult part, lol. It's hard to get a read on him when he's always into everything, so I started taking pics of him on the rare occasion I catch him daydreaming. Add a pic & send a pic never gives any indication it worked tho. Other than that, I think it's a splendid app, and the FGS itself is such a helpful tool that a lot of brilliant ppl obviously put a lot of hard work into. TY! =^ ^=

Fantastic app! I really appreciate the updated design. It's very intuitive to use, and the learning tools and tests are purrfect. The Feline Grimace Scale doesn't just benefit veterinarians and their teams---it also empowers caregivers to spot acute pain in cats sooner, allowing for quicker intervention. Since cats are experts at hiding illness, their pain often goes unnoticed. Thank you for your important research in this field. It's all about helping the cats!

Hi, I noticed that you updated the logo app. Now it's kind of off-center :(. Can you guys fix it, please?
