Advice: cat attacking dog since been spayed

Hi all,

Got my cat spayed on Tuesday, she was ok yesterday but today she is clingy and when ever she sees my GSD she has started to attack him. He hasnt hurt her for her to attack. Any idea what could have caused her to react like this? Will be calling the vets tomorrow but in the mean time any advice really appreciated.

Thank you.

all the smells are wrong after a day at the vets. we often have hissing between mum cat and her kits when mum comes back from being spayed. it normally settles quite quickly. suggest you keep cat and GSD separate for now, and call vets in morning as you said.

Thank you for your reply midgecat, its just confusing and concerning as she hasnt attacked my other dog or cats.
