we have been getting a cat strolling in our house as if it owns it ,vicious nasty thing scratches and hisses if i try to get it off furniture etc .the other morning at 6oclock i could hear meowing then realised the blinking thing was walking around the house ugh!.it's not a stray as i've seen it go through a bedroom window of a hose near ours every day .
stewey we havn't been here long ,7 years , must say when we moved in the garden was in a terrible state ,digging by back door we uncovered loads of cat skeletons about 4or 5 ugh!
poor moggy its looking for a new home, bless, show the poor mite some kindness, leave some food outside when it shows up it will soon change into a nicer cat its not the poor things fault maybe ? shame on you guys hose it water pistols at the ready may you never be homeless and hungry or come back in another life as a cat.
I have just found this question - it is amazing how cats just take the p!55 out of us humans and take no heed of our attempts to control them.
My first two solutions would be
(1) Lead the cat out to where you found the cat skeletons and explain that they had been intruders that you 'dealt' with in the past.
(2) Shut all the ways into your house bar one and rig it so that when the cat tries to get in there is a huge noise that will, hopefully, scare it away so that it won't come back. A friend of mine tried this and rigged her cat flap with pots and pans, the smug brute never returned.
You say that you have two cats - they may be very stressed by this intruder. Cats seldom look stressed but that doesn't mean that they are also unhappy with the situation.
Scaring it off might seem cruel but as long as he is not injured it is a reasonable course of action. He will then find some other home to visit each day for a feed.
