My girl will be 7 years old in October. Up until about a month ago she would have breakfast between 6-7am & then be straight out exploring, now she has breakfast & then shows no interest in going outside or nods off for at least an hour afterwards. Still likes to be outside a fair bit especially in the evening. Appetites not changed & no issues at vet check 6 wks ago.
FWIW shes my 6th cat but I can't remember seeing such an obvious (what I assime it to be) shift in energy levels with my other cats approaching their mid life
