How do I get my cats used to my kitten?

Question

The kitten acts perfectly fine around them. The cats get really scared and start doing a bunch of weird stuff then running away.

Answer 1

Just give them time.  I have 3 cats ( 5yrs, 1 yr, and 10 wks) they all acted weird when first introduced but soon each learned his place and learned to respect the older cat who happens to weigh about 18 pounds.  I would watch them closely for awhile until they are used to each other. Just to make sure the bigger cats don't hurt the little one.

Answer 2

Unfornatley this is what pets do when they are introduced to other pets. just give them time. they'll soon be find  

Answer 3

Well Mr. Phelps, this happened to my cats too. ;-D The older cats will get used to it in time. It may take a few days or a few months (my cat took quite a while to recover from not being the "baby" anymore), but it will happen.

To break the ice a little, maybe keep them in the same room for a few minutes. Get a toy mouse or something and then play with them. If the cat gets uncomfortable then take her out for like 10 minutes. Give them 10-20 minute "sessions" together.
