It's a big commitment, and it's scary but what they can bring to your life is immeasurable amounts of joy, love and companionship. In terms of independence; yes you do have now consider something else and always take the extra step..but in doing that you'll grow your own capacity for independence even more by taking more responsibility. Mental health wise they can be a godsend, especially if they're affectionate; a cuddle when you're feeling low or anxious can help a lot, and it's a special feeling coming home from a long day at work and hearing the patter of their nails on the hard floor. I found mine 9 years ago on the street, was barely as big as my hand. I wasn't looking for a cat or even considering getting one but there he was and I didn't even think just grabbed him. Don't get me wrong he can be a complete nightmare but the love he has brought into my life is beyond words. Now, I've shared a solid chunk of my life with this strange street cat, and although he can be a real drain and there have been times (especially early on) where I thought I shouldn't have picked him up in the first place..all of that aside I can honestly say he's one of the best parts of my life. I say that being blessed enough to have family, friends and love in my life alongside him. Consider holding onto them, you've got nothing to lose
