I’m really worried about my cat. He’s normally very affectionate - loves being outside but comes in the house every few hours or so meowing and seeking attention. He normally sleeps on the bottom of my bed every night. I recently went on holiday for 9 days and since I’ve been home he’s a different cat. He will only come in the house if I pick him up and bring him in. He’s eating less and has lost a bit of weight. He’s grooming excessively. I’ve fleaed him so I don’t think it’s that. Normally I would just attribute this to the british heatwave we’ve had. But the strangest thing is his new found hatred of the hallway. He’s ok in all other rooms but as soon as he leaves he runs SO fast down the hallway and out of the cat flap without stopping. Tonight I tried giving him some treats to lure him along the hallway but when he got about half way down his leg started twitching and then he legged it down the rest of the hall and out of the cat flap. This makes me think it might not be in the hot weather. I’m really worried and miss having him in the house! Any advice would be appreciated.
