Is my 1.5-year-old cat sleeping more due to age or a health issue?

Hello, that is a lot of sleeping! Sleeping all day is pretty normal for an older adult cat, but I would not consider it normal for a young cat like Leo - a 10 month old kitten should be active and playful. Since Leo is new to you and you're just getting to know each other, it's possible he's just a lazier kitty - but I would recommend having him checked out by a vet to make sure there isn't a health issue that needs to be addressed. If he were my patient, I would recommend running bloodwork, including a FELV/FIV test, to screen for any illnesses. If bloodwork was normal and he is eating & drinking well, then I'd reluctantly conclude he may just be a lazy cat....but, again, it's worth having him seen, if you aren't seeing the normal activity and playfulness that kittens usually have! Hope that helps!

Moxie is such a handsome boy! While older cats do slow down as they age and sleep more, it can also be an indication of an illness. The best thing to do is have him checked out by a vet, and I would take him into the vet this week for a check up. Best of luck, I hope this helps!

If Ludo was active all day, and is eating and drinking, then likely he's sleeping because he's simply tired from the full day. I would not worry about the temperature or wetness of his nose; it is not used as a sign if illness in pets because it can change to warm and dry simply by the animal sitting in the sun or near a heat source. I would monitor him for now, let him rest from his busy day, and if he continues to be lethargic for another 24-48 hours, then I would bring him into the vet for a health check.

Certainly as cats age - and at 10 years old Jack is considered a "senior" cat - they start to sleep more. However, cats often give us almost no real signs that they are experiencing illness other than an increase in the amount of time they are asleep. So it's easy to write off what is truly "lethargy" as just more sleeping. It may sound like an unimportant distinction, but in a species that is so difficult to interpret, I'd always default to getting a checkup before just assuming that this is a normal change associated with aging.

Ajax is an older boy and while he can slow down with age, this increased sleeping could be due to a medical illness such as arthritis (it's painful to move), a systemic illness, or infection. I would have him seen by a vet today if possible for a health check.

Older cats do tend to sleep more than younger cats, but if this is a sudden increase in lethargy, then I would recommend that you have Smokey checked out by a vet. After a thorough physical exam, the vet will probably recommend bloodwork to check for internal medical illness, such as diabetes, infection, kidney disease, etc. If the bloodwork is normal, they may discuss changes that have occurred around the house, or may recommend a trial of pain medications in case Smokey is painful from arthritis.

Sleeping more than normal for more than one day is not normal. Sometimes a cat may sleep more after a busy night out. However if this lasts through the weekend or if your cat stops eating or appears lethargic, you should take her to your vet on Monday for an exam and possibly a blood test.
