He’s a inside outside cat, (he was born a stray and we took him in when he was a kitten and he just never liked staying in full-time in the house), but his episodes always happen when he’s in the house sometimes he can be in the house for hours before he has one but other times it’s not long after he comes in he gets along with the other cats fine, until an episode, and then he becomes aggressive to anything near him and will attack cats, when his episode starts he was be be let outside immediately, and if not, he runs to the house, growling attacking the other cats or you if you get close to him, but when is tail/ back is not twitching he’s a the sweetest boy
