Yet another cat introduction query
Need some advice on a cat/kitten introduction that I canít tell if itís going ok or not. Iíve always had cats but never had to go through an introduction before and feeling out of my depth!!
Initial resident cat is Lana who is 4 years old, 13 week old kitten is Milly, both female.
Milly spent the first few days in a bedroom with no contact with Lana. Lana was hissing just at the new scent on our clothes and hands. Lots of growls from Lana at the bedroom door. This settled down after a few days and we struggled to keep an active kitten in one room. We separated the house into 2 during the day time with a glass door between the 2 zones.
Milly doesnít care about Lana at all...she sees a new playmate. Lana looks at Milly as though she wants to kill her. No contact is made, just the visual through the glass door when we try and feed them near the door.
Lana has stopped most of the growling and itís just hissing. She seems curious. We allowed them into the living area together which actually went ok. They had dinner near each other and chilled in the living room with minimal fuss. Continued to separate at night and when we went out. Have caught Lana chasing Milly in what I wasnít sure if it was aggressive or the start of play. Lana will lay down on the floor with her back turned to Milly and tuck her feet in/wash her bits so seems relaxed.
They start to play chasey where it looks like Lana is having fun. The fluffy dancing and chasing kind of play. Lana never really got fluffy until now. We can have a really good day where they seem to be ok and then the next Lana is just hissing at Milly.
I feel a bit safer leaving them alone but still not willing to do so. Lana seems to be going backwards and is more hissy. She can be chasing Milly (playing I think?) and then hiss as Milly turns to chase back. They canít touch nose to nose or brush up against each other.
Is this going ok or is Lana never going to accept that she now has a sister? The hissing is really concerning especially as we think we have made progress one day and then the next she canít stand the sight of her. Lana is quite territorial of any beds and isnít happy to share many household items but can also just sit and watch Milly play with her toys without much care. Seems like a moody girl?
Really want them to be friends so will take any advice good or bad...we know we went too fast but donít know how to fix it.
