Awww poor guy � besides losing a friend he�s also having to be in a strange new house�cats can be very attached to places. It�s possible there are odors and urine spray and scent gland markings from previous cats � you might want to scrub the entire place down with Nature�s Miracle. Has he ever experienced a move since he was taken away from mom as a kitten? Cats are very smell oriented, and I�m sure you know about how they spray because their own smell comforts them. Although of course its totally obnoxious to us humans!

Keep up with the Feliway � how long has it been? It can take some time for it to kick in (they say up to a month).

Try non-alcoholic Valerian tincture. Valerian has an anti-anxiety effect without "tranquilizing" ... no slowed reflexes, just a less anxious cat.

This is not a 1-shot treatment, it's long-term therapy.

Look for a brand that has 1000mg per ml and give the cat 1/4 ml (5-7 drops) morning and evening for several weeks, until the distress has faded. Then taper off the dose over the next couple of weeks.

I've moved a lot with cats. Most of them have been very clingy for a couple of months after each move. I just give them all the time and attention I can. They usually adjust to the new surroundings.

But also check to see if there is something in the new environment that is causing stress. One apartment I had was right by some railroad tracks. When the train came through that first day--oh, the poor cats were terrified. They ran and hid in the closet. But in a couple of weeks, one of them ventured out and peeked out the window at the loud, scarey monster, and within two months, they didn't even twitch a whisker when the train came by.

So there might be a noise or vibration somewhere that is causing your cat some stress.

Thanks guys! These are good tips! And camlam I think you might be right. I noticed he marked right next to where the A/C is located. It's rather loud when it turns on. I am wondering now if that sound scares him a little bit.

It sounds to me like your cat needs a companion so that he won't be so lonely when you're not home. Have you considered adopting another animal companion for him? A kitten may be just what he needs to redirect or calm his neediness. I would not recommend adopting an adult cat, or you may run into territorial and/or aggression problems, and his marking behavior may worsen. But a young kitten poses no territorial threat, so it wouldn't exacerbate his marking behavior.

It's something to consider.
