she spends most of her time inside the house but does play outside as well. Last night when we called her to come in to eat (she normally runs to us when called) we had no response. we found her lying in the garden by a bush. she refused to get up or to come to us. when we picked her up we noticed the cahnge in her behaviour. she seemed lethargic and dazed. we got her to eat some tuna and gave her some water but she didnt want dry food or even her favourite treats. she could still walk on her own and jump onto the couch as usual but she didn’t want to really move. she also showed no signs of any pain or a fever. this morning she went outside and we haven’t seen her again today at all. she is not coming when we call or for food. we have searched for her but to no avail. i wanted to take her to the vet this morning but she dissapeared so quickly and now i dont know what to do at all. any help or advice would be greatly appreciated. The onset of the behaviour change was extremely sudden and she is never away from the house for more than 2 hours.
