I would like to gently say that I think Dragonchilde is doing what she feels is best right now for her kitten and is asking for any ideas and help. She doesn't need to be treated in such a manner and told she is being irresponsible when she just wants some advice.
Especially for just a little sneezing.

If your kitten still has a good appetite and the mucous hasn't become thick and yellow then keeping his hydrated and eating and warm is the best you can do. Add water to his canned food and make it a bit soupy so he gets more water. If his breathing becomes more labored, the junk coming from his nose becomes thicker in consistancy and yellow and he starts getting goopy eyes then a trip to the vet would be warrented. At that point it is a definate infection and must be treated with antibiotics. I am sure if you are short of money most vets will work out a payment plan rather than allow a kitten to suffer. Especially if it is only a temporary thing.

Good luck with the kitten. I hope he is feeling better soon.
