Cat hissing at her sister cat after returning from the vet

Help!  One of my cats -age 3- got dehyrated and constipated and had to be with the

vet for 30 hrs to save her life.

 

Her cat sister, litter mate, together 24/7 since birth now hisses and growls at her since

she came home. 

 

I was shocked this could happen. 

 

Any advice?  We are on day 3 of this behavior.

she can probably smells the vet and associated stuff on her or sees her as a new cat

 

my cat jumped me the other night while on her "patrol" 

cats are funny little things

Yes, the vet first warned us and then we talked with her later.

 

Feliway, or a defusser is what she suggests. We ordered one.

She smells the vet, I had this also happen, only lasted a short time and my two kitties were back to loving each other.

This has happened with all the cats I’ve ever owned, but once the cat that has been to the vet cleans herself the problem always went away.

@petepetey your cat's behavior is normal and shouldn't last long. When my cat Popeye broke his leg, he was in the hospital for 6 days. Bringing him home made one littermate of his turn on him. Sassy hissed, slapped at him, growled, the works, but she eventually "forgave" him for coming home smelling like the vets. I think it took almost a week to get over it. Now they bathe each other, cuddle together, even more than before.

Re: Cat hissing at her sister cat after returning from the vet

I agree with all the other answers.  This has happened with all of the cats I've had over the (many!) years.  I've always been certain it's the scent of the vet's office and any medicines or anesthesia.  It's also always resolved itself after a few days, but it's always made me feel bad for the kitty who isn't feeling too well.  Like double jeopardy!

 

I've used Feliway plug-ins in the past, when a new cat has been introduced to the mix and found them to be very helpful in calming things down.

Re: Cat hissing at her sister cat after returning from the vet

I've had a lot of cats and every now and then this has happened; but it's been after a visit to the vets.

 

Here's my theory.  The hissing cat smells other cats on the cat that visited the vet's.  The fact that it was there for a few hours probably means the 'smells' got on the cat.

 

Even though the stay home cat knows it's HER buddy, she can probably still smell the other cat's smells on her.

 

Just an idea but it kinda makes sense doesn't it.  If I were you, I'd take something that you know has a strong smell from both cats and wipe the cat that went to vets with it.  It doesn't have to be wet (best not to be) but the smells will get on the cat and it MIGHT make a difference.

 

Please let us know how it goes.  This is just a guess.  I don't know if it was why but when I did it, it stopped the hissing.  Not right away but I did it a few times that day.  It eventually helped.

I just texted my friend who has worked for my Vet for over 25 years.  I'll let you know if what I suggested she agrees with.

Re: Cat hissing at her sister cat after returning from the vet

I am going through this right now. Whenever I send LuLu to the groomer my other cat Atticus thinks I have brought a new cat home. Have to feed them seperately but it only lasts for 3 days. Try white vinegar on a towel and rub both of them down a little to neutralize the odor. Good luck!
