I guess I should've asked how long this would last when I picked it up. Storm hated the medicine and it made him drool a lot but I think it works quickly because he then found his favorite box and laid down. He spent the whole night here and was still in it this morning when I went out to feed the cats. There were no more new urine accidents so this confirms the fact that it's been Storm all along.

Storm is still very sleepy today but this is to be expected for the first few days. He perked up when he smelled food and he ate a good breakfast. He then wanted to go back in his box again but I wanted to make sure that he didn't need to use the litterbox. I took him over to the litterboxes and I put him in one and he did pee a little bit. Then he laid down on the carpet again. He's very relaxed and everyone seems much calmer now. I'm still using the feliway plugins and I think I'll continue to do this for quite a while because they've been helping Starr with his stress issues. I'm also still spraying the hallway and entry way in the morning and at night. I hope that this new medicine will continue to work for Storm. Please wish us luck. Thanks.
