Peachie, other longtime kitty owners help! Our first kitty was Missy. We have had her about ten years now. We got our second kitty, Fred about six years ago. Not a single problem. Three years ago, we rescued Iggy (female). Missy *hates* her. Iggy is a meek and timid little girl. She was abused pretty badly before we got her. We know nothing about her past as she just showed up at my uncle's house one day. Hoping she would go back to where she came from, we waited six months then took her in. Once she was in, we could tell that she was house-broken, and abused by how she acted. She *is* litter box trained. The only iffy thing about her is whether or not she was ever spayed. Our vet couldn't find a scar, but she was estimated to be 8-12 months old when we got her. I would guess closer to 10 as she had been outside for the six months. She has never went into heat nor did she have a litter during that time so we (including the vet) think she was spayed. The only way to know for sure would be to cut her and that is pretty drastic. If she ever does go into heat, our vet will work her in that very day as he also felt she has been spayed and didn't want to put her thru the surgery just to check. Six months ago, we rescued Itty Bitty (female). Nothing has changed with her so she is not the problem. Missy absolutely is refusing to be civil to Iggy. She has went so far as to stand stretched out over the litter box to keep her out of it when she needs to go when the people who live here can see it! We bought a second box and Missy has laid claim to it, too! Before you people say we need at least three boxes, these are the LitterMaid boxes so they are always "clean" when somebody wants them. I really don't think it would change things if we had a dozen in the house as it is an Alpha thing. Our next tactic is going to be locking Missy up in the bathroom all day long with a litter box and water dish. She can't keep the others out of the boxes if she is confined. At first we considered locking her up in my bedroom but I decided that isn't fair to the others who sleep in my bed. (Missy will not allow Iggy to cross the threshold coming in here either) I don't think hitting her with a blast of water will be very effective as she LOVES water. She sits in the shower and asks for a bath. When I spray my hair she hoovers wanting to be spritzed in the face. Does anybody have any other suggestions?
