Uh oh!!

First I wanted to say, Sebastian is soooooo cute. I too have three sibling 7 month old kittens I rescued from a barn. Presley was a later addition too, because no one else wanted him. And since I had Perla and Perkins his siblings, I took him in too and don't regret it for a moment.

I always get so worried hearing stories about "out of the box" problems. It is such a tricky thing, cats and their litterboxes. I guess at this point I would first clean that area completely with an enzymatic cleaner. NOK out or Stink Free (petsmarts carry that one) are the best in my book.

Take Sebastian to the vet for a urinalysis. The fact that he squatted and voided out of the box could be a sign of an infection and just has to pee alot. It doesn't seem like marking to me since he squatted. So that would be the first thing to rule out. Since he is newer, he might have a bit of stress going on too. Does he seem comfortable with the other cats?

Then I would keep Sebastian in the bathroom for a couple of days to get him back on the right track. There is a litter called Cat Attract and also get those plug-in Feliway diffusers and they have a spray you can use. I like that too, but you have to lightly spray the area they were going every 12 hours. The diffusers only cover about 600 sq. ft. so make sure you have enough to cover you footage.

Your trio of brothers are all so beautiful and I am sure you can get this resolved.

5 litterboxes and cat attract litter in all of them... I know it is not going to look the best, but it will help... Put one by the door close th where he was squatting...

Don't forget to clean the comforter in enzymatic cleaner! I'm wondering with all the newness and stress if he doesn't have a UTI or something. A quick urinalysis and/or urine culture will tell you.

Maybe he should go to the vet, just incase something is wrong with his health.

My cats will always pee on cloth things bunched up on the floor. It seems to just be something that cats do. I wouldn't assume a litterbox issue or a health problem (unless he starts peeing on other things). Just remove the comforter and see if that helps.

That is good news!! Bleach that comforter . Your babies are sooooooo darn cute.

Kara, you really should take him to the vet to rule out an UTI...
Then Feliway on the walls, and the rest you know... 5 litter boxes, all open with cat attract litter... Feliway spray works well too - specially on your bedroom - make sure to spray your bed if he has access to it.
I know, your house will be full of litter boxes, but what is better, really?
I would be tossing some Nok Out or Anti Icky Poo (enzyme cleaners) on the laundry when washing those blankets. If you can hang them somewhere to dry, even better - the enzymes need some time to work...
No more blankets on the floor, no more laundry baskets on the floor either.
Take a deep breath, and work on solving the problem... Remember, you just went from having 1 cat at the house to having 4. Sebastian is in a brand new home... Even though things look peaceful, there is a fair amount of stress going on...

Please heed ALL of Carolina's advice, and get him to the vet!

And as Feralvr pointed out, the things on which he peed must be washed with an enzyme cleaner. And now that you've got 4 cats, Nok Out is probably a great investment: http://www.nokout.com

I have a kitty that stress pees on occasion and if one of the other cats is bothering her (which doesn't take much since she tends to start trouble with them.. ). You can adjust to picking up after yourself, it's really not that hard. Siri has never shown any interest in laundry baskets (aside from wanting to sleep on clean laundry), furniture, or anything on the bed - hopefully your boy is much the same.

Fold the blankets - get a quilt rack or something for the ones you wanted handy in the living room. Make the beds, or at least straighten the blankets a bit. Use a laundry hamper with a lid.

Hopefully you can get this straightened out and with a few modifications on your part it doesn't become a habit with him.

Oh no Kara, but this is an issue that can be solved.... Especially with an introduction if that is the case...
Do you have a room you can put him for a proper intro? If I remember correctly, an introduction was not done with them, right?

I edited my post as I just realized that is Seb... He doesn't have a brother...
Kara, I do think that if this is not medical, and if it is in fact a dominance problem, it can be solved with a proper intro... I really really do....

First thing get that urinalysis done. Then I would confine him to a room for a few days so he starts using the litter box regularly. Did you talk with the foster mom? He was fostered right, I think you mentioned that. Just to run the prob by her and get ger thoughts on the situation. You don't want this to become a habit for sebastian and I think he just needs his own space right now even though you think they are all getting along, there might be something going on between them you can't notice.

I would also suggest going out and buying a black light. Stink free sells one and I got mine at Petsmart. Use the light at night and turn off the lights while you are scouring the floor for any areas that might have urine. If there are other areas you didn't know about the black light will target the areas so you can treat them with the product. Don't pour the mixture in the center of the spot if you find any. Start about eight inches out from the spot and circle around the area and fill it in to the center. This will also relieve your mind if
you don't find any spots. Good luck at the vet and hope all gets better
soon

Kara, with a little time and patience, this can be fixed. I'm really surprised at the foster lady - stress is normal in any transition, and to assume it's a dominance problem without a vet check is just foolish IMO. It's also very sad that she doesn't know to suggest you go through a proper process of introduction, which helps resolve the dominance issues.

especially since dominance is 100% expected from the resident cat whenever you bring a new cat into the environment
I think you have such high chances of success Kara... You don't seem to have the extremes in there, the fur flying, the fights, the hissing...
Here is the article for proper introduction... I hope you give him a chance... We will be here for you hun http://www.thecatsite.com/Behavior/49/Id-like-you-to-Meet...-Introducing-Cats.html

Hi Kara
How is the situation with Seb over there? Hope all is alright... Did you start an introduction? Is there anything we can do to help?

How surprising for a rescue, they can't reach their potential for success if they don't know how to counsel people.

Anyhow, I agree with all above suggestions. Couldn't have said it better myself. I went through this when Hestia first came here and it was a long haul but it got resolved. I think it would have resolved sooner if I would have known all this great advice beforehand. It's fixable, hang in there.

More Were you able to get him to the vet before the storm? Was a UTI ruled out?

I agree with the this is solvable .. and am APPALLED at the rescue saying give back it is a dominace thing... Not so at all and HOW many homes has a 7 month old been in?

IMO and experience, most cat rescues and shelters will try to assist the new family with any issues they can so the cat can stay in the newly adopted home. I did, however, have this experience with one of my brother's newly adopted cats in my area. The cat my brother adopted was doing the same exact thing as Sebastian. Peeing on beds, blankets and pillows. He had called me for advice. They took the cat for a full work-up at the vet and everything came back totally normal. They said it was a behavior problem due to something in the home the cat couldn't deal with. My brother did not have any other cats, but had two little poodles. These dogs were chasing the cat and my brother and his wife had no control over their bratty dogs.

The foundation requested the cat back when my brother called them. The lady was not very nice at the foundation my brother said. They were extremely upset about the cat, but the rescue demanded the cat back. So they returned the cat to the rescue/shelter. I kept tabs on this cat, and found out it got re-adopted to another home with cats and was totally happy, healthy, and using the litter box. This was a year ago, and the cat is still doing just fine in the new home.

I am usually a proponent for working through issues, depending on the problem. And in this case, those dogs were so spoiled that it was cruel for the cat to have to live with being chased all the time and living in fear.

But, in Sebastian's case, there is no underlying, obvious reason for him to be having litterbox issues, so it surprised me as well that the rescue organization just bailed on helping you with Sebastian's peeing prob on the first phone call to them. Usually, in almost ALL cases, they will do whatever they can to help you work through the initial adjustment period so the cat can stay in the home.

How are things going??? Is Sebastian doing better??

But they took the cat for a full work up - and demanded kitty back after they found it was being terrorized by dogs. That makes sense to me.

yes, it was in the best interest and well-being of the poor cat. I advised my brother and my SIL not to get another cat. They don't have control over the dogs enough for a cat.

Like I said, most all rescues will do EVERYTHING possible to help kitty stay in his new home and they multiple access to many resources to assist, with good outcomes too. In my brother's case, the foundation did the right thing demanding the cat back, because there was going to be no training those dogs and the cat would suffer.
