HELP! what can I do? background we have a cat, she's 13 now... last year, a stray kitten found us and wormed her way in to our home/family. our cat hated her....just total hatred for this new stray... update: a year and 3 months later, my old cat has finally accepted the new cat, and all the hissing and swatting crap has ended. they 'tolerate' eachother ok, the here and now: 2 cats are at my back door...they are well groomed, one is bigger than the other, but they either come from the same litter or one is the mom, the other a yearling? They have the same markings, i think they are related somehow? they are throwing their bodies against our storm door and reaching up , trying to come in...when we shut the door, they jumped on the window sil and sat there and watched me while meowing...(scared me to death, when i first saw them in the window! it has been 3 days now. The hubby has shooed them away countless times....my cats are making noises i never knew existed and throwing their bodies against the glass door to get to them....my elder cat, and the stray that found us, are actually ON THE SAME SIDE....wonders never cease! it's been warm and rainy....they are sheltering themselves under the tarp we put over the 2 cords of firewood we had delivered. What can we do? friday a cold cold cold front is coming in. we can NOT take in these cats.... I think they are someone elses cats just lost...they were too groomed and too healthy looking to be just strays, (my stray was skin and bones, when she found us) BUT what if THEY ARE someone elses cats and just lost? IF my cats were lost and a freeze coming, i would HOPE that someone else would take them in, so they would not freeze to death....die.... I DON'T KNOW WHAT TO DO.... what can i do? i've never seen the cats before.... we only have about 10 people living off of a 3 mile long road....i do not think these are cats from one of the neighbors on my street...? we don't have a local paper that i could run an ad in, about lost cats... if i bring them to a shelter, they could be euthanized? PLEASE HELP!
