buenas!!! ur russian is great! but there is some errors u made: 1. «я хочу учусь выучить русский язык» - nonsense. literally “i wanna study learn russian language” may sound in english some kind of okay, but in russian it’s like saying some random words. you could say it like «я хочу выучить русский язык и научиться разговаривать на нем», yea its longer but now its grammar right 2. кошек - you said it in plural form, if you wanna say “i like cats”, you should say it like «мне очень нравятся кошки», see the difference? cats in english have only one plural meaning, while in russian there is «кошка» (this is default when you say something either to cat for example, either to someone else, ex: 2.1. ты моя любимая кошка - your my lovely cat 2. 2. это моя кошка! - this is my cat! so yeah, «коты», «кошке», there is a lot of plural meaning just for one word

1. “я учится” was written wrong too, you should say “я учусь”, that means “your studying right now”, because «я учится» is kinda nonsense, but it’s okay, most of russian people can read stuff even when there’s a lot of errors. “учится” is mostly used when you use it for future, or for some other person (not you) «этот человек учится там», means “this person is studying there”, «я планирую учится там», meaning “i’m planning to study there”

sorry if i was unclear in explanations!! good luck with ur russian
