Cats 2.0

Congrats on Clay   I recently introduced a kitten to my other 2 who are very bonded. The cat I thought would be a problem does well with the kitten and then easy going sweet cat is still hissing at the kitten 3 months later.  No idea.

Things that have helped? Lots of love, cat treats, play and catnip.  Also I invested in Feliway which is like a glade plug in of feline feramones that are supposed to mellow everyone out.  I have one upstairs and one downstairs.  I think it has helped.  You can get them at any pet store. I am trying to get Tucker, who is the one with a problem with the kitten, to understand he will still get lots of love from momma because it appears to be a jealousy issue.  Now that the kitten is stronger (He came to me with a broken leg and ended up needing an amputation)  he is getting bolder about challenging the older 2.  If he gets in someones face he needs to fight it out, if its unprovoked someone gets scolded.  Of course I have no idea what happens when I am not at home and I had to protect the kitten quite a bit at first as he was in a cast, then sick, then post op.  If your others know certain commands make sure to be teaching Clay those words too.  Kitty is learning NO right now.  I guess eating together is a big deal if you are a cat so try to inch their bowls together slowly.  Even eating together separated by a barrier is a good place.  I would also suggest checking out animal planet and or look at Jackson Galaxy's page. He is a cat behaviorist and might have some good tips for you.  Good luck

Thanks. There are some definite territorial issues, Jackson is OK with Clay in one part of the house, but the living room is turning into an MMA cage match I had no idea cats could make that much noise.

So the Feliway worked for you? It didn't seem to do much for my ex's cats. I'm going to try some catnip.

Feliway helped but did not resolve the situation.  Catnip is a much cheaper alternative and works about as well its just really messy. There are certain places  that are pretty much Tucker territory and I won't let Oliver (the kitten) go there.  Mine do eat together but they are all food motivated.  I am trying to play with them a lot.  tucker mostly sits y and watches but occasionally will join in.  If the LR is a problem maybe try to get them all together in neutral territory.  I actually have it pretty good but quite frankly I am tired of the growling after 3 months and am inclined to let them fight it out sometimes.  It is getting better I am just surprised its taking this long.  To be fair Oliver was in a cast the first 4 weeks then had a sick paw then had surgery and was post op so despite the fact he has been with me 3 months we have had only about a month of normal kitten so far. I am not the most patient person in the world

Another good idea to try is making sure each cat has its own litter box.  Each having their own area to go seems to help with the territory issues.

Feliway can indeed help.  Litter box: n+1 where n=number of cats.  Unlikely to happen when n=3, but make sure you have at least a couple for 3 cats.  More than 1 food dish as well.  There should be plenty of vertical space i.e. cat towers, backs of couches, etc, where they can/are allowed to get up high.  Most cats, as mentioned, can learn to peacefully co-exist, provided they have each have space to retreat to.  There may be some lost fur as they figure out the hierarchy.  And some incredible noise.
