It means you should take him to the vet
You should typically be 12 years old to drink protein shakes!! :)
I have included a link to a page that will calculate your cat's age for you.
Catherine "Cat" Osterman is 34 years old (birthdate: April 16, 1983).
At 15 yrs old a cat is 76 human years old. At 20 yrs old a cat is 96 human yrs. old. This is from a reliable publication. Figure about 85 yrs old human years at 16 yrs old.
A 16 year old can absolutely take protein shakes for fitness. They are safe and they provide nutrients all ages need. Nothing will hurt a young person in these shakes.
If a cat is 12 years old, then it has been asleep for 7 years of it's life (in human years, not cat years.).
Now that's an old cat, usually they only live around 14-16 years. In human years your cat would be hovering around the early 90's mark
The cat would be 20 in human years, although I've never heard of a cat living that long. The oldest cat I've ever heard of (and met) was 16 (human years).
Your cat should be around 60 cat years old in human years. Aging occurs much faster during the first 2 years of a cat's life. By the age of 2, a cat will be around 24 years old in human terms. After the first 2 years, a cat will age approximately 4 cat years for every human year. If your cat is 11 years old now, it should be around 60 cat years old.
The cat will be 112 in people years. Ok now listen if you would have listened to your math teacher you would know how to figure it out.
Cats can live into their late teens or early 20s, so there isn't a set age where a cat is considered too old. It's more about their overall health and quality of life. Regular veterinary check-ups can help assess your cat's well-being as they age.
