Hi there....I am Bigrougabagel's aforementioned wife. I am a certified Veterinary Technician with over 9 years of experience. So now that you know I am not blowing smoke, here are some general recommendations for your new furry baby
1. Studies show a combo of wet and dry food are probably best for cats of all ages. Unlike us and most other mammals, cats usually don't chew dry food unless it is a large size kibble. Thus they don't really get a benefit from the abrasion of the chewing motion like humans and dogs do. Also they are obligate carnivores, which means they MUST have a majority of their diet comprised of protein. High protein diets such as this are hard on the kidneys, so most well cared for cats run into kidney problems as an end of life issue. Feeding wet food along with dry helps to up the moisture content and water intake, which is easier on the kidneys. Also if the kitten is recently weaned it will likely eat better if water is added (not milk, most cats are lactose intolerant) to soften the food as it transitions.
2. Store brand foods are usually a low quality type of food. Kitten Chow is better than a store brand (Special Kitty, etc) in most cases, but IAMs, Eukanuba, Science Diet and IVet are usually even better brands if you can get them. You won't need to feed as much to achieve the same nutrition and they often have fewer additives, colors and preservatives. Before feeding a raw diet PLEASE PLEASE PLEASE research the hell out of it and consult your vet. A lot of folks feeding raw diets don't supplement them properly and the pets end up lacking vitamins and minerals as a result.
3. Behavior.....a lot of folks have mentioned not to play with your kitten with your hands and feet and they are 100% correct. What they learn now is what they will do later. A 1 pound kitten nipping your finger may be cute but a 12 pound cat out and out biting when they want attention is most definitely not. If the cat is biting then remove your hands or feet, say NO if you like, but then redirect it to other play with a toy of some sort. Cats need lots of activities or they get bored, which leads to destructive behavior and often obesity. Socializing your cat is important also.....getting them used to different situations can make traveling or boarding later in life much less stressful. Keep the cat carrier out so they can wander in and out of it and become used to it. PLEASE always transport your cat in a carrier. Yes I have watched a scared cat that jumped out of their owner's arms run into traffic and get hit by a car....not so much fun.
4. Please do take the kitten to a vet, and I believed you mentioned you were looking for one. Just an FYI.....you get what you pay for, so when you are shopping around please compare the services you are getting for the money. If they are vaccinating they really should do an exam to make sure your cat is ok to receive those vaccines. Cats are masters at hiding conditions until they are emergencies, so keeping up on care is important. Checking a stool sample for intestinal parasites is important. Most vets will likely deworm your kitten but no 1 dewormer gets all parasites, so checking to make sure there are not others is important. Several intestinal parasites that cats and dogs carry can be transmitted to people, so thats another reason to get it checked.
5. Another poster mentioned dental care and this is also an important part of your cat's health. You CAN brush your cat's teeth if you work on it as a step by step method. It is also a great way to bond with your cat because it becomes a routine you do together. Your kitten will lose it's teeth between the 4-6 month period, and you may not even notice them, but you can start getting him used to having his mouth handled beforehand. Cats are very much "What's in it for me" types, so make sure that you reward the behavior positvely. When the cat lets you stroke his mouth or lift his lip giving him a treat or a play session with a favorite toy will link that good feeling with your handling of his mouth. You can progress from lip lifting to running your finger around his teeth to actually brushing. DO NOT use human toothpaste as the fluoride will make them sick when they swallow it (and they will). You don't even need toothpaste, just a wet toothbrush or washcloth will be abrasive enough to clean the plaque off their teeth. Try to do it 2-3 times a week at minimum and it will make a HUGE difference. Studies have shown that routine dental care can extend your pets life upwards of 5 years, just like with humans.
6. In regards to declawing I will say this.....it's really up to you. If you do decide to declaw it is best to do it before they are 4 months old. With proper pain medication it is a minimally painful procedure...BUT GET PAIN MEDICATIONS!!! If you can train your cat to scratching posts and keep their claws trimmed it may not even be something you need to consider. If it becomes an issue of the cat destroying the furniture and you are considering giving it up, declaw the cat.
7. Lastly, litter.....most cats take to the litter box with minimal training. Unscented, clumping litter is usually best. Scented litters are nice for us but can be too much odor for the cat and cause them to avoid it. Cheap clay litters tend to be very dusty and can cause airway irritations in some cats, as well as being harder to keep clean. Keep the litter pan in a separate, quiet area from the rest of the house and away from the cat's food. Most cats do not like their food/water near their litter pan and this can also cause problems. It is not a bad idea to have 1 litter box/cat and 1 extra on top of that. Gives the cat options and if they are super fussy about the box can also keep them from going in the corner. IF your cat starts peeing/pooping outside the litter box and you have cleaned the boxes and not changed the type of litter, get them checked for a urinary tract infection. What starts as painful peeing can lead to litter box aversion and a habit of going outside the box. The majority of cats surrendered to humane societies are there because of inappropriate elmination issues.
OK I think I am done....lol. I know this was a huge amount of info but it's what I talk to people about every day. I have done my best to give a general outline, but again, if in doubt see a vet. Most things start small and are cheaper money and emotion wise to deal with when it is a minor problem than if you leave it go. Good Luck with your new kitty....mine are a joy and I hope your's will be too!
