Good morning. My 6 yo,adult female cat, is having a hard time. She started gagging about a week ago. Serious gags, I wait to see what she is expelling from within, and nothing. Along with that, she swallows hard, often and has lost her meow. She was very vocal, and can't meow more than a squeak. This comes within days of losing a new rescue kitten. I read of dysphagia. Any other suggestions, would be greatly appreciated. Thank you.
