We have two toms, just over 2yo. One of them is of a delicate disposition. Anxiety induced cystitis at every change. Mostly, we can fix it. New baby meant he was shut out of our room for a while, cue the pissing in corners and looking sorry for himself. Solved when baby got a little older and the feliway diffuser was replaced. Local cat started coming in through our magnetic cat flap, the pissing started again (they are usually happily outdoor and no litter tray) solved with microchip cat flap. However, our next door neighbours recently adopted 5 rescue cats, and they are all now spending a lot of time in our garden. I think this is why our little boy is now pissing EVERYWHERE that's not outside (poos still outside though?) what can we do? We can't keep them out of our garden, we have a new feliway diffuser, ensuring lots of water, and cystophan etc, but will he eventually get used to the intrusion, or will it always stress him out? Our 6mo dd will be crawling soon, and as much as I love him I can't risk a situation where dd discovers the puddles before we do. Any advice?
