I know as a majority of pet owners we tend to initially feed our cats dry kibblet food, but understanding a cats natural and designed diet will better help understand how to feed your cat! Cats are naturally born to hunt and shred and tear meat and where they get a lot of their water as well and dry food causes a lot of GI and urinary health issues! It can cause renal and UTI problems by nothing giving enough water in their diet and also kibblets they tend to swallow more whole since they're not small dogs, which than tend to swell in their stomachs and can cause vomiting and GI issues such as developing food sensitivities and allergies! I had a cat who would vomit almost 1-2 a week and it was scary and I switched him to an all wet good diet and also a all natural hypo allergenic diet from hill science which you can get from your vet or RoyalCanine from a pet store. The thing is, yes store brand cat foods are less expensive but think about it a bag of 7.99 car food that last for 2 weeks etc or more, doesn't that sound interesting at all!! Do we live on food like that? Yes spending extra money on more natural healthier diets can be pricey but it can prevent more higher cost for vet visits! Not only did my cat become better but he thrived! The first thing I suggest to all Cat owners is WET cat food all the way and second try and find a food that is as natural as possible! A lot of store brand car foods like meow mix or the cheaper store brands are full of fillers and meat left overs that aren't even safe for human consumption, do you want you cat eating that? Yes you may not have issues especially at a young age feeding foods like that but like my cat by 4 started having many stomach issues and allergies to foods! Many owners think feeding flavor like chicken and especially seafood are the best, which if I could state anything seafood flavors even though they tend to be appealing to your cats they create a majority of issues lacking amino acids and containing harmful chemicals, even though these brand foods add additional nutrients and missing supplements that's like McDonalds doing the same to a double whopper doesn't really make it any better for the body! So spending a little extra I believe is more important than settling on poorer diet for the cats we love so dearly! I'm not saying to go all wet because I say so even though I believe it's the best and my vet has informed me the extreme benefits to it but i definitely say if you do have dry food in the diet make sure it's a smaller percentage than wet!! And most important of all please please please if possible invest in the most natural of cat foods! Science Diet has worked miracles and I have heard good things about RoyalCanine! Now on to Grain free, a lot of people thing because as human grain free and gluten free diets are so beneficial it's the same for pets but really more food allergies are to the fillers, higher carb than protein diets and allergies more specific to the actual protein itself! Especially feeding the same form all the time! The best proteins and easiest on a kitty's tummy are duck,venison, and beef. I tend to suggest avoiding chicken and especially seafood! As for dry food and the theory of helping keep teeth clean there's specific healthy weight control or hypo allergenic treats that's can help with that! It's the basic facts that cats are like humans what goes into our bodies really plays a role into how well it performs and if it's something you wouldn't dare eat id say it's not fair for your cat either! There's always coupons available online and I went from spending 18-25$ a month on dry cat food the cheap store brand to 45$ all natural hypo allergenic and it's a bit pricer but it was worth seeing the amazinf health changes in my cat and better than the original $500 vet bill to understand his vomiting, plus it helped greatly with his Coat meaning less grooming and prevention to hairball obstructions cause wether it's throwing it up or passing through bowels it's still something that can be harmful or painful to the cat! If you see your cat with signs of hairloss, vomiting, constipation(especially with dry food) and diarrhea I'd first look at it's diet than on to what might be more serious issues which again can always be prevented early on with a healthy diet! I wish I would of known earlier on about this! I use to focus more on cheap prices and wet food covered in thick flavorful gravies and even though your catty seem to love the flavor what's going on inside the body is more important!!!
