Haven't noticed whether it's after grooming. Noticed it when she walked into the room when I was on the PC; then later, when I got home from shopping, she was sitting at the top of the stairs with her tongue out. She seems happy, and will play if I entice her, but I've noticed that she's sleeping in the corridor upstairs, which is a cool part of the house. Neither of my cats have been very hungry during the hot weather - they always get like that in the heat.
Sam's sitting by me now, purring, with her tongue in. I've noticed she's been seeking more affection than normal. She doesn't usually want to sit on me when it's hot, as my lap makes her too warm.
Will keep a close eye on her.
Can't imagine what could be wrong, unless it's just the heat.
She sometimes gets hayfever, but hasn't been sneezing.
Her fur looks a but dull, as though she needs to give it a good wash! I'll brush her tonight, she likes that and it's usually therapeutic.
Any ideas would be appreciated.
