Veterinary questions? Ask a Vet for Answers ASAP
Hi, Welcome to Just Answer. I'm Chris, a small animal Vet based in the UK. I am reviewing your question and will get back to you as soon as possible
Just a few further questions in order to give you the correct advice, how old is shew? Is she eating and drinking normally? Does she go outdoors?
It sounds as though she may have a upper respiratory tract infection (laryngitis/pharyngitis), this would account for the change in her purr and the retching symptoms. It is likely viral in nature and will self resolve, your vet may be able to prescribe an anti inflammatory for her to help ease the symptoms and reduce any fever she may be experiencing, so it would be worth getting her checked over.
I hope that answers your question? Please let me know if you need any further help or advice.
If she is still eating, drinking and bright in herself then it can most likely wait until Monday.
It may do yes, do keep any eye on your other cat for similar symptoms.
You're welcome. Hope she is on the mend soon!
