Night before last, I noticed that my 10 month old cat, Gollum, was breathing very fast while laying next to me on the sofa. Yesterday his behavior was very different all day; he didn't sleep on the bed with me, didn't follow me around the house, not interested in his favorite toy, no interest in his favorite treats, didn't snuggle up next to me on sofa, didn't come running when I filled dry food
dish. Each time I checked on him, he was sitting in a position I call a cat loaf, with his elbows sticking out to the sides and still breathing rapidly. He slept from 9pm to about 5am. I checked on him every hour and rapid breathing continued. This morning he ate some dry food, used litter box to pee and his breathing has slowed a bit. No sign of diarrhea
, he purred when I pet him, which is a normal thing he didn't do yesterday. He is 100% indoor cat, has had all his shots, was neutered February 18th and seemed to recover and was acting normal up to Saturday night. There are no chewed up plants, no chemicals or poisons he could get to. The only odd thing I noticed was his 2 foot tall cat tower he likes to sharpen his claws on was tipped over. Since he ate, drank and used litter box and his breathing has slowed down, should I just watch him for the next 24 hours or should I be rushing to vet clinic right away?
