How to Figure Out Your Cat’sAge

If a cat is adopted or a stray, you may need to use other clues to estimatethe age of your feline friend. Below are a few general guidelines, but these characteristics will vary between cats, depending on health, previous care, and circumstances. For best advice, consult aveterinarian.

  • A cat’s teeth: In general, the older the cat, the more stained the teeth. White teeth means that the cat is probably younger than 1 year. If there is some yellowing, the cat might be between 1 and 2 years. Tarter build-up on all the teeth may translate to age 3 to 5, but keep in mind that certain cats are more prone to tartar build-up than others; certain diets may promote tartar; and the lack of tartar may just be an indication of previous dental care. Missing teeth may mean that the cat is senior, although health issues and other causes (such as previous dental surgeries) may also result in the loss ofteeth.
  • A cat’s coat: The older the cat, usually the thicker and coarser the fur. (Keep in mind that different breeds/mixes will have different coat thicknesses, and may naturally have fine or thick fur at any age.) Senior cats may have patches of white orgray.
  • A cat’s muscle tone: Younger cats are muscular and older cats often are bonier with extra skin; as they age, their shoulder bones may protrudemore.
  • A cat’s eyes: Young cats have very bright, clear eyes, usually without any discharge, depending on health and breed. As the cat ages, the cat’s irises may appear jagged. A cat with eye cloudiness may indicate a senior, but there are health conditions, some of which require immediate care, that also can cause cloudiness. (If you kitty’s eyes are cloudy or watery, or if she is squinting often, consult a veterinarian as soon as possible. Certain eye conditions can get worse quickly, and cause more discomfort, if not treatedsoon.)

My cat, Gilligan is 24 years old. He is still very active and super friendly. In the last few months he has been throwing up almost daily. The vet says he is fine. I did have to start giving him pumpkin with his food to digest better, but I don't know what else to do. Any advice would be helpful.

Older cats have greater issues with furballs. And need to be treated for them. passed on through the generations, the older cats were given fresh fish cooked gently to just cooked. Inspected for bones. Crumbled in the water. Cream heated till warm, not given at the same time as fish, and chicken liver, cooked gently in hot water and provided with the water after removing any tough parts. Old cats often have teeth issues. Bath old cats in oatmeal water (no soap) and dry with dryer and brushing to get the lose hair off. PLace old cat in front of fireplace. Then clean the claw marks from your arms. Long rubber gloves or towel around old cat will protect you next time.

Please go to another veterinarian, vomiting and cat, especially daily is even grass daily is not a good sign. It is not normal. I went through this with my cat too. I thought it was just grass hairballs cleaning out his stomach like this was routine I was wrong. It ended up being IBD and he has been on a daily steroid for two years now I cleaned up his diet and he is maintaining. He is 15

Ever since she was a kitten my cat would throw up at least once a day. My vet said she was fine. Thirteen years later, my vet retired and I got a new vet. This vet put my (now elderly cat) on 5mg’s of prednisone for 12 days. My cat stopped throwing up. A few days after we stopped the prednisone my cat started throwing up again. So, my now 15 year old cat takes 5mg’s of prednisone every other day and hasn’t thrown up in 2 years.

When cats become elderly it actually is common. Even stiffness and arthritis can make cats throw up. Have you tried putting the food on one of those feeding platforms? You know, it's just a little thing that raises the food off the ground (and water). Our older female threw up a lot, crouching to eat food scrunches up their stomach and can make them throw up, especially when they're old. Raising the food up about two or three inches (you would want to look size up) made a big difference.
She still throws up sometimes but it's rare, previously it was worrisome!
Plus they really like it, they all like eating food off raised area!
I didn't buy a platform I just use old cat food boxes 😆😆 even the little round tubs that have traits in them and just flipped them over. LOL I don't have money for all that fancy platform stuff. The Cats don't care.
But if you want to buy a raised platform be careful, because it looks like most of them were probably designed for dogs and they just say dogs/cats - but they don't look right for cats.
Has to be the right height for your cat's size, we have a tall Cat & 2 little cats, I just put little boxes, tubs in different places and the tall cat always eats off the taller stuff, etc. But they all really seem to enjoy eating off a plate or something that's raised off the ground.

Please take your cat to another veterinarian to have her evaluate again. Vomiting is not normal, and by doing do so, your cat is losing nutrients and calories.

My little calico Luna is 20 yrs old and going strong. Before her I had Sprinkle, another calico, for 18 yrs. Calicos seem to be a hardy breed.

My calico is 27 1/4 years old, she still eats, drinks, rests well. She is skinny, stiff back legs and does not groom at all, her slinky fur is course and knotted and I can’t brush through it anymore. She has fair and poor days. I think it’s time to let her go but somewhat unsure.

My grandmothers cat was 26, his appetite was fine. He didn't groom himself to good anymore. So we had him shaved. He lived about 2 more years just fine.

Actually calico is not a breed but a color. You can have a calico color coat in just about any breed.
