I dont have the time to go thru all 4 pgs of this post right now, but i'd like to put in my 2 cents.
Kittens are always underfoot, thats wht they do. Learn to walk around pets, watch ur toes and be very aware what ur putting ur foot on b4 u put weight on it. Hard to describe it, but i think i kinda keep my toes to the floor as i step vs have them pointed up and step down heel 1st. Watch ur step and ur more likely to nudge the cat vs actually step on them.
For fleas, frontline and such will have to wait a few months. I saw frontline at costco the other day for $30 and a box should have 3 mos of treatments and its well worth the money in my opinion. If you can get it at petmeds.com that will be a good way to go, and any vet will carry it and/or the other brands like it. A couple brands treat more than just fleas. Don't forget to treat ur home as well when u have fleas. They make sprays and powders for ur carpet that are easily obtainable at wal-mart look in the pest control section or carpet care sections. Where i work we often treat fleas in a safe non-pesticide way, works great on kittens. We wash the pet in dawn dish soap and let it sit 10 mins b4 rinsed away. We usually follow up with a kitten or oatmeal shampoo to help restore oils to their skin. Dawn is powerful stuff, its what they use to clean animals in oil spills. Advice b4 giving a cat a bath, trim their claws so they can't completely shred u. I have one cat who i bathe regularly and hes totally cool with baths, my other cat don't like them but she handles them fine. I bathe cats every once in awhile at work and most they usually do is try to crawl away and yowl. Restraint is key, hold their scruff or have some sort of restraining device. At work we have restraining leash things we loop over their head and under one front leg so they can't choke themselves.
Deworming is always a good idea, and ringworm is a totally different thing altogether. Ringworm does happen but its not near as common as the internal parasite. Ringworm is an external fungal infection. Cats will get bald spots over night and the skin will be dry and sometimes flaky, it sperads fast untreated. Children pick it up easily, but adults usually have to have broken skin (cut, scratch, sore) to get ringworm. Cats need vet treatment for it, human treatment is easy, buy an anti fungal cream like lotrimin (yes the athletes foot stuff) Oh and on a human its a distintive red/pink ring, usually small and the skin in the ring is dry and they ITCH. Yes ive dealt with ringworm b4, once in a set of foster kitties and several times on myself :P
I hope ive givin good info and not repeated what too many others ahve said since i didn't read all the posts :P I've gotta go get a shower and get rdy for bed for work in the morning. Take care of the baby and give him a hug and kiss for me :) I'm a total sucker for kittens :D
