Ummmm...autism?
Did you fill her drinking bowl full of Beer again? She appears to be drunk.
Take her to your vet. Tell him what you are observing your cat doing and see if the vet thinks it is something to be concerned about. It's probably nothing, but better safe than sorry.
he mighta had a stroke,takim to the vet
It sounds neurological. Take it to the vet immediately.
She could be poisened. Call a vet. My friend had a cat that was doing that and she had had an allergic reaction to Frontline Plus. Seek profesional help!
Any time an animal is lethargic, they need to be taken to a vet. It's one of the main signs of illness in cats and dogs.
Sounds like something hit her in the head get her to an emergency vet right away, please. I hope no one hit her does she go outside? VET now!
Do not pass go GO TO THE VET. Anitfreeze, other poisons. This is not good. GO
my cat had the same thing ages ago. shes dead now. (she didnt die from that). but she was ok. but take her to the vet anyway :(
she is having a seizure and needs to be seen by a vet IMMEDIATELY...is she dehydrated? this could be the cause of the seizure...dont try to hold her or touch her until the seizure passes just keep her from any danger (like bumping into furniture etc) but she definately needs a vet visit really fast
have you recently treated her with over the counter flea medicine? zodiac, bio spot, or the worst-hartz? or have you over treated her with advantage or frontline? the staggering and falling down sounds like conditions related to overdosing on flea chemicals.you may want to get her checked out by a vet ( yes i know everyone here will hate me for that) but no one on here can diagnose what really happened!!
you should take her to the vet. A possible stroke..even though it's not common. You still want to get her checked out. That would be wha'ts best for her.
OOH that might be bad,VET.
It sounds like she's either having a stroke or a seizure. There's not much you can do except to try to keep her comfortable. Definately contact the vet as soon as possible. They'll be able to tell you what to do from here. One of our cats occassionally will lose control of his back legs and shows several of the same symptoms as your cat. Fortunately it doesn't happen often and the symptoms wear off after several hours. I hope everything goes well! Good luck!
shoe could be seizing, i.e, having a seizure, so you should probably take her to the vet...
take her to the vet NOW...sounds like epilepsy, diabetes or poison like a few people answered. Don't wait..go NOW..whatever it is, its not good
Vet ASAP
your cat probably had a stroke if this just recently happened. he probably has head or brain trauma.
You need to get her to the vet she could of had a stroke or something.Please get her checked out as soon as possible.
