My vet had gone fishing(LOL)so it was a very nice female vet instead.
She thought Chico had beautiful teeth,not any sign of tartar,so,he is a Poster-Cat for canned food and she agreed,at 14 yrs old,he has never had his teeth cleaned.
She was 100% against feeding a cat kibbles
She looked at the earlier results of his bloodwork(done end of April)and noted his T4 was 38,so it's on the higher end of normal.
The browning of his fur,could possibly be from that,but she was not too concerned about it,his little white hairs everywhere were from old age.
So,I'll be checking his weight and have another bloodtest in a couple of months.
