Have Cat Questions? Ask a Cat Vet Online.
Hi my name is***** and I am a licensed small animal veterinarian, are you online so I can ask you some additional questions?
I would be concerned with the dilated pupils(mydriasis) that it is possible you cat could have been exposed to a toxin of some sort, have you or your neighbors recently dewormed their cats or dogs?
What is your kitties name? How is the breathing now?
I am sorry I do phone calls at this time, I can put the case out for other veterinarians is you which to talk by phone, or we can continue to talk via chat
I cannot do phone calls is what I meant to say*
I would also be concerned for other issues such as neurological trauma, or other toxins such as ivermectin(a dewormer), or antifreeze or brometalin(rat poison). How is your kitty doing currently? Are the pupils still dilated?
Based on the symptoms that you are describing(dilated pupils and shallow breathing) after being outside and the possible constipation, I would recommend to contact your veterinarian as I would suspect they would want to see him right away
Is he current on his vaccines such as rabies, and FVRCP?
Also dilated pupils could be the results of something serious going on with the eyes or even high blood pressure.
