Dweezy's ear was SO hot when we have tried testing him, as he was in the sun.

He mustn't be a bleeder. I think he was holding onto his blood on purpose. LOL.
Anyway, we are going to get some urine sticks on the weekend and do that, and also try his ear again on Wednesday.
Ahh, and yes, Lyn, we can definitely AFFORD to book him in for the whole day at the vet for a proper curve...he DID actually go to the vet three weeks ago at 8am, to be picked up at 5.30pm, but...they got the first test...and then that's it. They put him in the cat ward out the back between testings, and when they came back for the second one, he freaked out, had what they called a major psychotic episode, was bashing himself against his cage, screaming and yowling, hissing, frothing, and had soiled himself and the walls of his cage with both pee and poop, from the intense fear he was experiencing. Whenever anyone came into the doorway, or he heard their voices just outside the doorway, he'd start screaming. They couldn't get near him.
My partner and her mum went to pick him up at 5.30pm and were given a large dog cage to bring home with him for everyone's safety if he was still freaking out. Once he left the cat ward, he was ok though. Very anxious (when he got home, he was sniffing my face all over and HUGELY clingy, with all wide black eyes) but calm. He was fine since then. No issues.
But this is why we are so concerned, because we don't know anything. He never got a curve done. We can't get any blood from his ear.
I think our options are...
1. Just keep trying the ear, keep him plied with endless treats, and also use the urine sticks
2. Get our vet to come to our house and take blood from the leg vein (I have heard that this is much less traumatic than trying endlessly to get blood from an ear if it's not working, and also taking blood from the neck vein)
3. Take him to the vet (which we are in 10 days anyway for his annual checkup and vaccinations), have them try to get blood from him (not the ear) and if that works and he's not freaked out, see if they can somehow do a proper curve WITHOUT him being put in that cat ward.
He's freaked out in similar ways before when he's seen neighbourhood cats outside our balcony doors / windows. He hasn't been SO scared, but he screams and you can't calm him until the cats have gone. He then will get scared and attack his brother Monty if he gets too close, as he doesn't recognise him. We once had to separate them for 8 days. We have had wrapping paper stuck to the bottom half of our windows for the last two years so he can't see any other cats. We are on the ground floor in an apartment block and cannot stop other cats from walking by or sitting on our balcony (the other day a little girl cat was grooming herself on our bench on the balcony. I had to quickly shut the glass doors and draw the curtains so Dweezy wouldn't see her. I can't go out there and shoo her away as then my boys will get out, especially as they'll want to see who's out there).
So maybe being in the cat ward with other cats nearby, being uncomfortable, having blood drawn, being shaved on his neck, and also remembering his previous times there (he'd been there before for surgery on his nose as well as his cornea, as he had been scratching them both due to a skin irritation), was just too much for him, poor little boy. He is ok in the other areas of the vet. The waiting room with other cats (in cages) and dogs...the vet consultation room he's ok. He's also fine when he goes to the cattery whenever we go away. He's been going there for six years with his brother. They can't see the other cats there, but they can hear them.
Anyway...yeah. lol
