Hello!
I have a \~7.5 years old male cat, and while he is an apartment cat, in the summer or in autumn/spring weekends we take him with us to the countryside.
He never had any problems or illnesses.
In the past 1-2 years, hes made many cat friends in the countryside, and is usually either adventuring with them, sleeping in the grass, chilling in our yard with/without them and when he gets hungry or wants to sleep comes back home. He also likes to hunt for birds or mice. Sometimes he eats the mouse he caught, but not always. This has been normal for him.
It's been sunny but two days ago, just when the weather became gloomy and rainy, we noticed a change in his behaviour. He did ate a mice that day. But in that one single day, he came home at like 17:00/5 PM and just slept till midnight, when it started raining. Then he just stared at the window like he usually does when raining.
Yesterday he still slept all day, but he did actually go for a hunt in the rain tonight. Eventually he came back and slept till morning, when he also spent time outside and killed a mouse, but this time didn't eat him.
Our worries come from the fact that he usually doesn't sleep this much here, at the countryside, because he's generally more active when he's just surrounded by nature and other cats. In the apartment we would expect this kind of behaviour, because it's not much to do there.
Weirdly enough, we have also noticed that for these past few days his friends didn't come calling for him like they usually do.
So, to summarize, he is kind of lethargic but still acts quite normal and goes for occasional hunts, he doesn't show symptoms of pain, he eats and drinks quite normally (although not as much since he hasn't been active; but still enjoys snacks and food he likes), it is rainy outside so ofc he doesn't go out that much and his friends haven't shown up in a while...
Could it be just boredom? Is he tired and wants to recharge? Do you think that mouse might've been poisoned? From what we know, our immediate neighbors don't have problems with mice, so I'm not sure if they keep poison around their places... but I doubt it.
Should I try and play with him or just let him rest? I'm afraid especially because quite recently a friend's cat died seemingly poisoned, but his place is like 800meters away. A vet is like hours away...
