ahahahaha, This made me chuckle. OHs family found two stray male kittens just over a year ago. one small black kitten and one that looks like a bengal X - blue in colour Due to them being extra small and malnourised vets put off neuturing them until they were at the adequite weight etc...however this was taking much longer than first thought. Over the past 2/3 months theyve noticed that the house always stank like cat spray, they never caught one of them in the act so wasnt sure which one it was. They resorted to keeping the cats downstairs (as whatever it was was mainly happening upstairs) and it seemed to stop. However two weeks ago they came home and the kitchen was trashed, spray everywhere and it wreaked. They have a catflap, which for the time being was locked (due to the males being unneutured) so went back to the vets who said they weighed 'just' enough to be neutured....so off the boys went (that was a job and a half to get them there) had the snip, came home and all was good. Until yesterday! OHs dad got up, went down stairs and caught a black cat spraying up his leather jacket which had fallen on the floor.....he went to pick it up and it ran off and dissapeared. So went back upstairs to have a moan to OHs mum....laid on the bed was the little black cat...OHs dad started ranting and raving, OHs mum said he was there the whole time.....so for months weve been blaming their cats...when it wasnt them! Turns out a black tom from the street has been coming into the house (somehow) and spraying up everything. hes broke the catflap so he can come in...but cant get back out, so we have no idea how hes getting out. Anyone got any ideas of what they can do? their currently looking into getting one of those magnetic catflaps...but any other ideas would be welcome.
