Hi all. So this is a bit of a strange one and I am currently at a loss as to what to do/think. My husband and I have 9 cats, all indoor only that we love very much. They have the run of the house and plenty of spaces and enrichment, good high quality diet and regular veterinary care. We have built shelves and walkways all over the house for our beloved kitties and a happier bunch of cats you could never hope to meet. SOOO... last night fairly late on I was disturbed by the sound of the letter box having something pushed through and all the cats running in to the front room... which makes me think this has happened before. I ran into the front room and the floor was covered in cat treats and the cats munching them.. there were far in excess of what 9 cats should have as a treat.. Well for obvious reasons I swept up all the treats and got rid.. as for all I know they were not only excessive but potentially poisoned. An anxious night was therefore spent making sure the cats didnt become unwell. My husband works nights and I also work some nights as we are both in social care, so it seems someone is deliberately doing this when we are at work late at night.. so not a child who wouldnt know better and just wants to treat the cute kitties. We have had several occassions recently when the cats have been vomiting overnight.. presumably due to being overfed treats in this way. I dont understand what possible motivation someone would have for doing this. We are concerned that someone may either be giving treats so they could poison the cats, or are attempting to lure our cats away or steal them. As I say they are indoor only so cannot be lured out but who knows if it will escalate to a break in? We know that a lot of cats have recently gone missing locally. We had yet another owner put a flier through this morning about their missing cat and there have been several recent posters or neighbours who have asked us to keep our eyes peeled for their missing cats because they know we are fellow cat lovers. We are now going to create a safety box around our letterbox to prevent any treats being put through but does anyone have more understanding of what the hell is actually going on here or what else we can do to prevent further problems? We are also planning to build a large outdoor catio but tgis makes me concerned for the cats safety outdoors.
