Skinny cat

Just noticed lately that my 13 year old cat has lost a lot of weight,eats good drinks good nothing more than usual,seems to be in good spirits as always,not sure what the problem is,she seems fine??

There are many reasons that older cats can lose weight, and most of them will show up on a blood test -- things like diabetes, hyperactive thyroid and kidney disease, to name a few.  It is really advisable to get a blood panel done to cover at least the basic blood chemistries and blood counts.  After that, you can address whatever problem is discovered.  A few other reasons she might lose weight include cancer, irritable bowel syndrome and bad teeth,-- being unable to chew properly, or having pain when eating so she eats less because it hurts.  I think everyone else here would say the same thing, get her to a good vet for an exam and blood test as soon as possible.  It is much easier to treat any problems when you catch them early.  If you don't have a regular vet, ask someone you trust to recommend one, or else look up an AAHA accredited animal hospital near you.  Remember, vets are people too and not all of them graduated near the top of their class.  To some it's a calling  but to others it's just an income.  Here is a link where you can see if there are any AAHA hospitals near you.

Thanks for the info,she has an appointment to get blood work done,it's just weird cause her gums are fine,nice and pink,she's eating the same,so it's probably something like thyroid or cancer!I hope not ,don't want to think about those things,she's my baby
