Safe Cat Vitamins and/or Supplements?

Hello, I usually read posts here on TheCatSite anonymously, but finally made an account in hopes of getting advice on a recent issue in my household. I have a 16 year old cat (Terry) that is starting to slow down. He is eating, but not much and I'm worried about the state of his health going forward. I would love to take him to the vet, but I am currently unemployed and already $1000 in the hole for taking another cat to the vet a few months back. Terry has generally been healthy for the majority of his life, even faced with being on a poor diet for most of it (he was my mother's cat first). As far as food goes, all the cats eat Nature's Variety Instinct Raw Boost. I have been feeding Terry a variety of wet food in hopes to get him to eat more as I thought it might have been his teeth. He stopped eating all cat food at one point and I was feeding him baked chicken, but I have been getting him to eat more cat food again recently.

I was looking up liquid cat vitamins in hopes of helping him improve a bit, but I'm not sure which vitamins are actually safe. I was considering Spectrin  until I read a review saying it had two toxic ingredients (I don't know which ingredients these art though). Terry won't eat any kind of vitamin that smells strong, and he hates the vitamin creams/gels. He will absolutely not eat anything that is mixed into food, so liquid seems the most reasonable as I can just administer it directly. 

TL;DR: Does anyone have any info on safe vitamins that come in liquid form for senior cats?

I don't know much about vitamins and minerals, but have you tried sprinkling Floriforta on his food? It's a probiotic, which is nice, but the main ingredient is animal digest, which most cats really love. It might get him to eat more. Also, have you ever given him baby food? It's not suitable to be a cat's main diet, but it's very mild and what I give to sick cats when I really need them to consume more calories. Gerber stage 2 chicken or turkey are great for this purpose. It's pretty appetizing to cats and very easy to lap up.

I'm so sorry Terry isn't feeling well. You probably know this, but without a vet visit there's not much you can do to diagnose what's actually wrong. If he's nearing the end of his life, which is a possibility, supplements probably are not going to do much and if he hates taking having medicine squirted into his mouth as much as my cats, it might be kinder to let him be.

In all honesty you need to find a way to get him to a vet. Adding vitamins or supplements to his diet without knowing what the real issue is isn't responsible nor is it safe. He could be in pain or suffering. I would look around and see if there are any vet's that have payment plans, or apply for care credit if you haven't already. 

I absolutely agree with M missmimz . It's really important to find out WHY Terry's lost his appetite. He needs to see a vet asap. Cats can develop hepatic lipidosis (fatty liver disease) simply from not getting enough calories for a few days. I appreciate that money is tight, but he really does need veterinary treatment.[article="32998"][/article][article="33011"][/article][article="33155"][/article][article="32915"][/article][article="30138"][/article]

Also, you might try calling local rescue organizations and see if they have any recommendations for low cost vet services designed for people in your situation.
