Customer Question

we have a 20 year old cat, he looks rugged. He is very thin and also he goes in and out of the house. He doesn't play he's mostly a barn cat....he has never put on weight and eats all the time today i noticed that he right eye is swollen and the 3rd eyelid is showing and the pupil is pinpoint. He's eating drinking and now napping on the sofa, but is there any thing i could do for him here at the house.
JA: I'm sorry to hear that. Strange behavior is often perplexing. I'm sure the Veterinarian can help you. What is the cat's name?
Customer: Frazier
JA: Is there anything else important you think the Veterinarian should know about Frazier?
Customer: no, he's been healthy but always skinny and he likes to hunt in the pastures and has had his shots each year.

When was the last time that Frazier had bloodwork performed?

What foods are you feeding at this time?

Customer: replied 3 months ago.
He eats soft food 9 lives and dry food 9 lives plus.... he has never had blood work, they come by and just give him his rabies and other shots.
