My cat Oreo is in her third heat cycle. 1st time she was very affectionate and was loud and was rubbing everything, second time in heat, she was affectionate and was trying to hump people and things, this time, she is very aggressive. she has came up to me more than once and has attacked me. growling and hissing and clawing. she has torn my hands and arms wide open. almost severe scratches that are very deep open wounds. she is now spraying and she attacked my other cats. she has also been shredding things.she has never acted like this before. she is a yr old. i had to throw a hoodie over her and carry her to the crate and force her in it while the whole time she is clawing, biting and hissing. i now have to keep her in the crate with the exception of letting her out long enuff to use litter box and to eat and drink. is this normal normal behavior?shes been in heat for 4 days already. i never had a female in heat be aggressive. my other female is quiet and prefers to run into the crate to get away from everyone when she is in heat.
